Customers that own a Chevy Silverado or GMC Sierra with the 6.6L V8 L5P turbodiesel Duramax engine under the hood can upgrade with a substantial power boost via The Pulsar V3 module from Edge, as featured in the following brief video from Holley.
The Pulsar V3 module from Edge is available for 2017 through 2021 Chevy Silverado HD and GMC Sierra HD 2500 / 3500 pickup trucks equipped with the 6.6L V8 L5P turbodiesel Duramax, which, in factory trim, is rated at 445 horsepower at 2,800 rpm and 910 pound-feet of torque at 1,600 rpm. However, as highlighted by this feature video from Holley, The Pulsar V3 module adds upwards of 136 horsepower and 291 pound-feet of torque, as measured on a dyno.
In order to achieve these impressive gains, The Pulsar V3 module controls four essential engine parameters, including the injection pulse width, injection timing, fuel rail pressure, and airflow. The Pulsar V3 module offers users five power levels to choose from, with increasing peak power figures, up to the 136 horsepower and 291 pound-feet of torque, as mentioned previously.
The gains are substantial, and not only give the 6.6L V8 L5P turbodiesel Duramax engine meatier power and torque curve, but also significantly improved acceleration. Per Holley’s testing, the factory tune yields a quarter mile time of 14.93 seconds at 92.32 mph, while the max power level with the new module yields a quarter mile time of 14.17 seconds at 98.44 mph.
Customers can use the factory GM steering wheel controls to adjust the power levels as desired. Additionally, The Pulsar V3 module allows users to tune other aspects of the onboard computer, including the speed limiter, TPMS, tire size adjustments, axle ratio adjustments, engine code clearing, throttle sensitivity, and more. There’s also a relearn feature that enables the Allison transmission to adapt to the new power levels.
Pricing for The Pulsar V3 module is set at $793.76, per Holley’s website (“Holley Days Price,” suggested retail price of $980).

Ordered 3!
probably a stupid question but will this void warranty?
No
Assume that the increase in performance is permissible in all USA states including Hawaii.
If so, very good job!
Only if they catch you will it void your warranty.
Any testing to see how it affects fuel economy?
I’ve seen increased fuel economy with mine
So is it still only making power by excessively dumping fuel and spiking egt and particulates? Or did they actually fix it?
I’d buy a banks over the edge pulsar any day.
@Kyle Vanwinkle That was the issue with V2, Edge fixed egt issues and made significant improvements with V3 and its substantially better than Banks now, numerous comparison showdowns between the two show Pulsar V3 beating Banks over and over, time and time again. I have the V3 on my 2021 2500HD AT4 and love it, no issues with 16000 miles
Edge has not fixed the issue. We’ve done dozens of dyno pulls with the V3. Measuring with an AVL micro soot meter, the V3 rolls just as much coal as the V2. It’s a soot machine, even in the tow setting.
Will it help me roll more coal?
I have the V3 on my 2021 Denali and love it. On 3 it runs like a Corvette and on 2 it still is a lot of fun plus it does increase my fuel mileage, both in town and on the highway. One night after midnight, a brand Mercedes AMG flew past me, he was showing off his new car to another couple but caught the light so I caught up to him. I was in one and popped it up to 3 and when the light turned green, he shot out only I kept right up with him, which seemed to get him upset as we cat and moused up to the next light we caught. He beeped his horn, I looked over and he pointed forward nodding, indicating he really wanted to race, so I popped it up to 5 for the first time and nodded back and gave him the thumbs up. There were no other cars on the road and we had about a mile to the next light. Foot on the brake, I locked up the converter and when the light turned green, I floored it. My truck’s back end went about 2′ sideways then shot about 3 car lengths ahead of him as he was smoking his tires and my truck hickupped a second then darn near threw me in the back seat as it really took off and I kept pulling away from him. I looked down and I was doing 118 MPH in a 40 zone so I let off the pedal and slowed down so I could catch him at the next light. He pulled up on my right, rolling down his window as I did and he said, “Man, that thing hauls ass, what did you do to it?” I smiled and said, “It’s stock.” I pulled away and he was shaking his head, wondering how a 7,000 lb. truck just wiped his butt in his brand new go-fast. Yes, I know he could have taken me top end but this was sure fun. That was my only trip to 5. I do know that I will have to remove it to have any warranty work done on it.
I would ask how long they will support it??? I bought an Edge Evo and found a out a few years later….they no longer support it! Only a $300+ investment but, it’s worthless now! Never buy one of they’re products ever again.
I have a 2012 gmc 6.6. I’m new to the diesel world. I got stuck in west Virginia because the def fuel injection was not working. So I had the truck deleted.
Can I still use your product on my truck?
