I have always been afraid to mess with my vehicle tune in the past. But after I got my Silverado and it had that DoD mode that switches into 4 cl mode I new I had to try something to bring the power back to it. This tuner was the perfect option. Very easy to use even for a first timer like me. I installed the 87 tune used firm shift option and turned off the DoD. It's a tire screamer now. Love this tuner already.
