ask mike@n54tuning i'm pretty sure he will give you a pretty good answer he resells everything BMS and is excellent on customer service as far as terry goes he is just as good as mike both those guys are highly regarded here in the forums.

btw: the dpfix is (mainly) just to prevent the computer fromm throwing an error when you are running catless downpipes or thats why most people buy it unless you are running a jb4.
