UpRev is for the owner who wants to do many mods and needs the flexibility of fine tuning. If you plan on things like just a CAI and exhaust, a simply flash tuner will do the job for less money. BullyDog makes them, Superchips as well as a few others. The main things you want is to remove the WOT restriction and maybe the ability to change timing advance and remove limiters. They all do that and more.
