Hey all, got a big question here. My 2002 Jetta has been having problems with overboost codes. It stared after I installed race pipe & 20 HP tune. From what I have found, it could be because my tune didn't have the 3 Bar MAP sensor in with it. I have trouble shooted all other possibilities for this over boost code. Has anyone heard of this happening with this small of HP upgrade not having a 3 Bar MAP sensor installed & tuned for it?
