I have a CAI thats it. On my way to work everyday on the parkway i set it on cruse to save gas . When I go up a steep hill the rpms shift to like 5 1/2 grand and my muffler sounds like a beast as my car takes off up the hill at the same speed! Besides affecting my car it kinda pisses people off becuase they think i am trying to race them. Like once I had my cruse set on 65mp and I was aproaching a very steep hill on the taconic parkway and besided me was a m3. We were about even as we aproached the hill and all the sudden bammm! RPMS to almost 6 grand and i shot up the hill at 65 like it was a shot of nos or somthing. Of course the m3 showed me no mercy as we got on flat grounds...Should I be worried about this problem? Cood it be the ecu from the cai?
