I wanted to know if anybody with a Pro-M 87mm MAS gain anything from it? I bought one and it gave me idle problems, it bogged and skipped rpms under hard throttle acceleration, and last but not least it made my snake feel slower. Any with similar problems? The only mods to the car are magnaflow muffers and Jet Performance chip. I called Jet and they said that the chip will adjust its self to other mods that affect the fuel/air ratio, injector curve and the mass air curve. Which the MAS does just that. I think Jet is full os s***t because no other chip that i know of adjusts its self. any help would be great. thanks
