This item did what it says it'll do. However, my trucks computer had some issues with this. My check engine light would come on due to loss of traction control and the engine would put itself in a reduced power state. I would then have to unhook the Pedalmax to reset the computer. I never hooked it back up cause I dont want to run the risk of jacking my trucks computer up.Helpful (12)

Big improvement in drivability
Installed today on 2017 GMC Sierra with 5.3 and noticed instant improvement in response. Both off the line and going down the highway. I bought kit with control knob, but unhooked and left at 100 default. Highly recommended to improve drive by wire issues. Very happy with results.Helpful (16)
I read in another response to a question that; 'This will not set any codes or show up when scanning the vehicle, and should not effect your warranty.' My Question; Can it be disconnected if the car needs to go to the dealer, with no issues, reconnected / installed the same way after?
This device simply routes and connects to your existing sensor from your accelerator. If you need to remove the device, simply remove the wiring and you are fully back to the original factory harness with no trace of the device being installed.
does anyone else have an issue with tripping check engine codes uninstalled to to dealer and This does show up in your bio's they new exactly what was installed 2017 silverado 6.2L
While this will not increase gas MPG, will it decrease MPG significantly?
You may see a slight decrease in MPG, but it can honestly depend on how the vehicle is driven.
Will this work with 2018 Silverado 1500 LT 5.3 8 spd trans with E assist Crew Cab????
This throttle enhancement will be able to work on your Silverado.
I have a 2009 sierra with 5.3 the truck is also a flex fuel vehicle will this affect anything will it still work
