hey zackqb2, i think you got that o/r x from me haha. how do you keep it from having a check engine light? i use the sct x3 works good, you feel a nice gain with a 93 octane tune, and if you dont already have mil-eliminators you can turn off ur rear o2s with it. but i cant tell you if its any better than diablo or sniper since ive never had those.
