Question
Do you have to use a different fuel grade? The ram 1500 5.7 runs on 85/87. Do you need to run it on 91?
By James Christensen on April 4, 2023
Answer
No, we have tunes specific to 87 Octane but the best performance/gains will come while running 91

Does as advertised

By Dick46 on August 6, 2019

Was skeptical but bought it anyway. Had my mechanic install it for me. Could not be happier with a product.

Fantastic - But

By bletz on December 11, 2019

Unvelievable, this is so easy to install and use, the power difference is amazing, BUT driving home last night my ram 1500 would not shift out of 1st gear, i had to stop, turn off the vehicle and re start to clear it. not sure what is going on, will keep testing to see if it does it again

19-21 ram 1500 pulsar

By Brady S on February 18, 2021

I’ve had my pulsar for almost a week now and so far it’s pretty good. I love how easy it is to install as well as having the option to switch tunes on the fly. I was expecting a bigger change but you can definitely still tell you’ve got a tune.

Installation Snag

By Dacapo on March 13, 2020

2019 Ram Rebel: easy connecting but truck failed to start. Removed it and truck still wouldn’t start. Towed it to dealership who advised 17 different codes were displayed. They reset them, connected the edge and have been fine since. The performance setting is off the hook! Gives you the true full potential of the truck. Economy setting is what I use. Picked up 2 mpg.

By Cblaise18 on May 24, 2021

Exactly as advertised

By Gringohulk on December 15, 2018

Install took less than 15 minutes and couldn't be easier. While it may not be as aggressive as a custom tune, the throttle response is perfect & and there's definitely more torque (very noticeable on hills while cruising, everything is effortless with little to no down shifting anymore). This is what was missing from this truck, it just feels right now. Side note: while I have cycled through the settings, I only use Performance with MDS Off, but it's been on for 2 weeks & 2300 miles with absolutely no issues at all. I will also add that I don't love the way it turns off MDS, it kicks in for a split second before the Pulsar deactivates it. No big deal, I simply use the manual shifter to keep the MDS off. I can't imagine a better upgrade in the $500 range.

Best bang for Buck and great tech support

By Dante on January 23, 2019

I bought the Pulsar Edge for my 19' 1500, when I got it, installation was easy, my RAM came with 22inch wheels from factory and a 3.92 axle ratio, however, the manual is confusing while adjusting these settings, it does not state that no changes are needed if they are default, then it does not state wheel DIAMETER, is states WHEEL SIZE, so I did put the wheel size, 22" in english mode, that started a lot of problems, such as cruise control not working, traction control warnings etc.. Got in touch with tech support, they were great, they sent me a new edge and we finally nailed where the problem was. It was a pain, BUT their tech support was great, I never felt like, "oh great I'm screwed". In performance mode, the Pulsar made my truck wake up, the way it should be. In economy mode, I did not notice any gas savings, but the throttle and power is adequate for city use, I don't believe anyone buys a v8 and slaps on an ECU for gas economy. It's not about the problems you encounter it's how you deal with them, they did what's right, I recommend it and would buy it again.

Awesome

By Travis t on January 20, 2019

Huge performance difference. Stock 0-60 is 6.5 in performance mode 0-60 was 5.6, throttle response is great! Economy mode provides awesome in town mpg. This is a must have, I bought one for Mitt my 2019 rams.

By dgray3046 on January 25, 2020

Works as described

By David D on July 7, 2021

Easy installation and works exactly as described. I bought this primarily to change tire size on my '20 Ram but the ability to turn off MDS and swap tunes on the fly was nice. Using the performance tune around town and then was able to quickly shift to Economy with MDS on for a long highway trip at the touch of a button.

2019 Ram 1500

By Randy G on January 21, 2020

The pulsar for my Ram 1500 5th generation works very well in doing as advertised. Although some have had issues as indicated in past reviews, At this time I am very satisfied with its performance

Verry good pruduct.I speek french. J’ai adoré le produits et je le recommande fortement

Edge Pulsar

By RamRebelHemi on June 22, 2021

This product works as advertised. Easy to install, performance mode is for real, I drive in Tow all the time. Economy mode is so close to stock it may as well not be there.

Good and bad. But mostly good. For now.

By TimA on March 1, 2020

This thing is incredible. Main reason for purchase was to change speedo once I lift. So much better than just that. The eco mode gives me +3MPG. Performance mode can break tires loose through 3 gears. Wild. And fun. So why 3 stars? Lineup marks for cables was off by a good amount. Plugged cables into Pulsar, and the guides were off enough that a portion of my cable bracket housing shattered. After that, a side of the Pulsar also shattered while trying to tighten down cables. Garbage material, shoddy craftsmanship, but the performance is worth it. Just would like to know it’s not going to fall apart for $500, and at this point, it’s still a question mark.

Sensitive Throttle

By Bergman on January 21, 2020

Makes a huge difference. I love drive in Perf mode with MDS off. However, the throttle is hyper sensitive and I constantly am spinning the back tires.

2 weeks and can't say enough good things about it

By ABNRGR on October 9, 2018

2019 RAM 1500 Limited 5.7L Hemi. I installed this within an hour of driving off the dealer lot. Unless you're a 6 footer it is a stretch to reach the bolts without a footstool. I did my install in a retail store parking lot. With that being said, once installed, the setup is easy. I adjusted for 3.92 gears and All-Terrain tires. I used the tire manufacturers numbers for the tire diameter and had to readjust to get the speedometer to match up with a GPS reading. After that, the Speedometer and MPG readings are spot on. The display readout at the top center of the gauge cluster, right under the RAM logo, is the best of any programmer hands down. The adjustments are instant and on the fly, just by pressing the up+ or down- of the cruise control. You see in plain English what tune is selected. It shares the cruise control up/down buttons so, if cruise control is set pressing the up/down adjusts your speed. All you need to do is disengage the cruise control, select the desired tune, and reengage the cruise control. I've been using programmers for over 15 years (A new truck every 3 years) and nothing has ever come close to the ease of use of the PULSAR. I like that the programs are stored on the PULSAR and the Truck PCM is not flashed, there is no trace if they scan your PCM. I'm 5' 8" and can change it back to stock, with a step stool, in less than 5 minutes. Just make sure you save the factory PCM mounting bolts. On the redesigned 2019 RAM 1500 the PCM is moved from behind the air box to the side of the battery box. Very easy access to install and return to stock for dealer service visits.

Pulsar tuner

By Hector M on January 28, 2021

Honestly this purchase was way worth it. Better than I expected. The performance setting takes the truck to a whole other level.

Absolutely Works on a 2019 5.7 Etorque.

By jim12 on December 16, 2018

Must update the unit ! The PULSAR unit may NOT arrive updated but once updated this unit 100%works and well. WOKE up the HEMI. DIFFERENT ENGINE with the PULSAR. Instant response and less Thottle needed to accelerate. More Power and Torque that I noticed. Possibly 30/30 respectively. Ask for the Update cable or opt for the "Insight" which is what I did and I'm Happy I did. The INSIGHT will automatically update the PULSAR and you'll be able to change ALL the settings from the INSIGHT, then you can either leave it attached to the OBDII or Disconnect it. I left mine attached because it provides much more info than regular tachs and dash...

Edge Pulsar - Love it!!

By Mayo on June 29, 2019

Purchased the Edge Pulsar for my 2019 Ram 1500 Rebel and have seen immediate result. Throttle control is unreal in performance mode and the horse power gains are impressive. Well worth the $$$!! Installation was easy and programming is easier. Great product!!

So far so good

By Shue2181 on September 12, 2019

I would like it better if the price was lower or at least give the cable and update often.

By joelderemer84 on April 8, 2021

Love this product!

By Jordan tampa on July 19, 2020

This is an amazing product, super cheap for all the benefits. I use the tow mode all the time and you can't even believe your pulling something I have 6x12 trailer and my truck is on 35s and I don't feel one tug

NEED TECHNICAL HELP!

By Jearledward on September 12, 2019

Keeps making my Electronic throttle control malfunction and locks the truck out at 15 miles per hour. Idle is up and down from 1k-1500k every click. HELP?!!!

2021 Hemi eTorque - Excellent Product - Go for it!

By john s on April 26, 2021

Works as advertised. Easy install just follow instructions to the letter. I used a little dielectric grease was only deviation. I purchased this for performance as most do. It really makes a big difference on takeoff as well that second gear shift getting into traffic. I combined this with the AFE intake install at the same time. It woke up the Hemi eTorque for sure!!

Worth Every Penny!

By Keith S on March 25, 2020

I purchased for my 2019 Ram 1500 5.7 4x4 and love it! Wish it would remove Speed Limit and allow me to turn off the TPS.

Great product

By Big Leeg on May 30, 2019

I've had the pulsar on my 17 ram 1500 for about 3 months now and I love it. I am averaging about 11 L/100km with 35 inch tires. I always have it set to performance mode mds off and only run premium fuel. Couple issues I ran into, mds off doesn't really disable mds so I always set my gear limiter to 8. And I can no longer see the tune level on my display. I hope soon they make so you can upload custom tunes

By loylombardo on January 15, 2020

Big Difference!

By Jorge M on March 11, 2019

really wakes up the Hemi, the econo mode is also great to save on long trips. Makes you wonder why RAM didnt do this.

Hard to beat for the price!

By Maxx on December 4, 2019

From a dollar cost value perspective I love it! Really makes the truck as it should have been from the factory. Been running mine for a few months with zero issues and lots of grins. ;)

Amazing!!!

By Mad Mike on May 6, 2019

I added this to my 2019 5.7. Amazing doesn’t cover it. Nay sayers want to say it just makes the throttle more sensitive. It does, however that’s not all. Shift points are much more aggressive as well as the timing. Out of my primary mods, I added the Pulsar first and it was great. Then I added a Vararam Air Gabber and headers. My truck is seriously a beast in Performance mode. As you may have guessed, I didn’t buy this for the eco mode which as you would expect is a dog as it’s designed to be. I leave mine in Performance unless I’m towing the boat. Rather way, the best mod I’ve made. In fact, if I made just one mod it would be the pulsar. Hands down.

2020 Ram 1500 Laramie

By Mike O on May 4, 2021

Works as advertised and super simple to install. To bad Edge did not send me the OBD Update Cable with the Pulsar as ordered.

great tune. Easy install

By BlueOvalDiesel on April 10, 2019

Woke my 2015 ram up. Just installed and so far I’m impressed. I can’t talk to mileage yet but it seems to be better even though I beat it a little. Only complaint is that it doesn’t have the option to shut off the speed limiter. I wasn’t expecting much in a gas tune, as I have had diesel trucks and tunes before which about double the power, but I can’t complain about this for a gas tune. It will turn the 33’s over with no problem. 5-star if speed limiter was able to be shut off.

Noticeable mpg & performance gains!!

By Rebel 2019 on December 10, 2019

Been over a month & I say this is a must have! Install took about 30 minutes including programming. I was able to update tire size for 35” & now speedometer is accurate vs GPS. RPM shift points are smoother & the steering wheel controls makes it seamless to cycle through settings on the fly.

Its Right but wrong

By Shmam on June 28, 2020

This programmer does work like it says but there is so many flaws with it, my ram 2019 has constantly been out in limp mode throws error for throttle response, electric traction control and wont go over 1,000 rpm the only reason i voted it 2 stars it worked for 1 month like advertised but failed to mention all big errors and damage this can do to you truck. IS IT A BUY OR NO?- only if you like to have a little more performance and save gas or to fix your speedometer to ride bigger tires but willing to deal with going in limp mod and check engine light and error codes dont bother you, the programmer would be for you!

Bighorns Personal Opinion

By William W on February 25, 2021

I only made this purchase to adjust the speedo in my 2019 Bighorn. Personally I keep it on the Stock setting, BUT when I feel like getting Dirty it goes in Tow Mode and when it’s time for Showing Off, it’s Performance Mode and Lighty Up my 35’ tires at will when that light turns GREEN. Great Product and it gets 4 Stars from Bighorn ONLY because when I called customer service NOBODY PICKED UP!!!!!

By orangewildfire on February 20, 2020

Wow

By Maps on July 26, 2019

I’m so confused to any negative responses to this product. My 2015 6.4 Ram woke up big time , it runs like a beast. I love the product , I love that you can change it super fast to your needs excellent product big thumbs up in my book !

The best of the best !!

By Racso on May 11, 2019

I bought the edge about 3 weeks ago and I have to say it change my truck to a mean RAM. The first week I put the edge on my eyes pop out with wow. It gave my truck that extra spark that it needed. For any one out ther I would recommend this product to every person I met , this product is absolutely amazing.

Great Features and Performance Improvements

By DerOldMan on June 3, 2019

Love the fact that this is a piggy back device vice something that rewrites the ECM. This ensures my warranty stays in tact. Just recently had an engine issue on my new RAM. If it wasn't for this feature, I am sure that my warranty would have not covered the repair.

Pulsar for my hemi

By D Taylor on January 28, 2021

I just installed the pulsar in my 2019 Ram 1500 Tradesmen. Easy installation and runs really good.

Good product

By Gabriel on January 27, 2020

The pulsar is worth it. If your looking to wake up that hemi, get it. Throttle response is immediate, even when changing modes on the fly. Use premium gas no matter what setting you use. First 2 weeks i used regular gas in eco mode and went from 16mpg down to 12mpg of in town driving. Then i used premium for 2 weeks and it got back up and is staying around 17.5mpg. Good product.

WORKS AWESOME

By Benjamin T on August 5, 2022

Works great you do lose the parking sensor functions. Installed on my 2021 limited night edition with the borla attak exhaust. It's like a new truck!!!

Pulsar 2020 ram 1500

By Michael Z on May 5, 2023 | Verified Owner

Easy install. Easy instructions. Test drove yesterday for a couple hours trying all modes out. Very Impressed with how it’s integrated with trucks factory controls. Reason I purchased was to change tire size, delete mds and tow mode due to when I haul a trailer. Stock with tow haul it doesn’t seem to be good at shifting well for lack of better words. Today I took it out with a little over 3k trailer load and was impressed with tow mode mds off. It’s what this truck should have been doing. This product is awesome! Highly recommend!!

Awesome tuner module

By Jason A on October 9, 2023

Easy to install, easy to change settings on the fly, excellent gains on economy, tow and performance. I would like to see in the description that this model will fit 2019-2022 Ram 1500 CLASSIC DS. It wasn’t very clear that this module would work on my truck but it does. The module allows you to turn off MDS in any setting which is nice. You can also select tire size and axle ratio to correct the speedometer. The module also adjusts your throttle sensitivity/response. Very noticeable on performance. You can purchase the optional harness for future module updates but feel that should have been included. All in all a great product, not many options out there without replacing the ECU for an unlocked version. Edge knocked it out of the park with this piggy back system. The module can be removed easily if you need to take your vehicle into the dealership for servicing. This module won’t leave any footprint on the ECU because it alters the signals after leaving the factory computer. Absolutely brilliant for vehicles still under warranty.
