Love this product.i have 2 of them on my cars. You instantly notice a huge difference in throttle response. Would recommend this product to anyone.

Service was great and product worked as described..... If your sick of lag in your truck this tuner works

Took ALMOST 2 mins to install, if they could make the install simpler that would be great thanks/s

I installed the Pedal Commander on my 2021 GMC Sierra Denali 1500 3L Duramax, and wow what a difference it makes! Took a few seconds to install, very easy (must wait 15 mins with the car completely off, key fob 30 ft away from the truck, and the door ajar before install). Once it was installed, I played with the different setting.Eco mode is way too slow, be careful as to not get rear ended while testing eco mode.City mode feels normal to me, nothing changes.Sport is my perfect mode, take off is PERECT!Sport+ I'm insane!!! A lot of power and would not recommend for city/highway driving.If you own the 3L Duramax, then you understand the sluggish takeoff… well, the best way I can explain the Pedal Commander is that your diesel will get the fuel economy of a diesel and the takeoff power of a V8 gas engine!!!I love the Pedal Commander!!!!!! Truly a must buy, wish I bought a long time ago.

I have 3 of these now and i love them.

Only complaint which could be operator error, it won't go into eco mode without using the app

I was doubtful about this products effectiveness but wow, it makes a huge difference. Easy install / easy upgrade. Multiple modes to go from gas savings to silly fast. Put a smile on your face everytime you step on the pedal. I never write reviews but this one deserves it.

I have purchased this for my 6.6 L5P Duramax as well as for my 6.2l half ton and they have both worked amazingly, doing exactly what they are suppose to do, with zero issues. The installation couldn't be any easier and the results speak for themselves. Excellent product and I highly recommend it.
