Bought this back in august for my 5.3L chevy and traded the truck off and no longer need this tuner. It is unlocked so you can program your vehicle without issue. Just have to enter your vehicle type and year and it will walk you through the process. have all the cables to update and the cd to download software if you ever purchase a custom tune. Will program gas or diesel!

You can go to diablo's website: http://www.diablosport.com/trinity/ to see if it is compatable with your vehicle
