Immense improvement in performance on initial tune. I am really quite pleased.

I think the Diablo Sport Tuner is a great investment for the money,it does everything they say it will do. And the menus are easy to navigate. It really woke up my Silverado, the multiple truck use is a nice option agreat s is being able to turn off the active fuel management

Intuitive interface. Easy to use. Made changes to tire size. Plan on a regear in the future. Was able to turn off TPMS. I was hoping to be able to create a increased idle setting for winching, but you must have the tuner plugged in when you want to increase engine speed. Did take a good 30 mins to flash on a new 87 octane tune. Did notice a little increase in throttle response, but not blazing.
