Can a HPP3 for a 99' trans am be used on the 2002 trans am?
Don't bother. They're junk for REAL programming.
Now if you want to change tire size or gear ratio for the spedo, temp the fan comes on etc, it's fine. But for actual "I'm tuning the car" programming it takes HPTuners or similar.
From what i know you cant use it on yours or on any other car if its already been used on a particular car, unless its unlocked. If its new or unlocked you should be able to use it for 99-02 but the answer is at the bottom. Hope it helps and if im wrong i apologize in advance.
