The programmer works great and has plenty of options and is easy to use. This programmer doesn't have preset programs like others I've had but the Hypertech has more fine tune ability.into haven't had a chance to play with it very much. I have it set fairly mild and I can definitely tell a difference.
Upgrade inboard PCM at dealership before use

got device, plugged it up with excitement only to find it wouldn't work. Called tech support and found out my truck needed updating before I could use. Finally installed but was hoping to correct speedometer due to tire size, still 2.5 mph off. Everything else works as it should now.
