Pedal Commander - PC77 for GMC Sierra (2019 and Newer) (5th Gen) 1500, 2500HD, 3500HD, SLE, SLT, Denali, Elevation, AT4 (2.7L 4.3L 5.3L 6.2L) For Gas Engines Only | Throttle Response Controller

I just installed this on my 2025 GMC AT4 and it works great.

Plug and play, followed the instructions and had no problems. Installed it on my 2025 sierra with a 3.0 duramax . Made a big difference in throttle response

Wasn't expecting all that much to be honest. Then, I LAUNCHED out of the garage and scared the crap out of my wife. Sport+(4) is no joke, be careful!! *UPDATE* 9 months with it and still loving it. Makes the truck more fun to drive. No issues with engine lights.

The peddle commander does make the throttle respond much faster than it comes from the factory. This is what it doesn’t do. It doesn’t disengage the top end speed limiter. It doesn’t increase your horse power. I’m not sure about the rev limiter if it disengages it or not. If your looking for something to give you a faster response time when accelerating this will definitely do it. It made my 6.2 420 hp get up and go with no hesitation.

Worked great!! Truly need this on every vehicle! The horsepower goes straight to the wheels. No more lagging.
