I've been having troubles lately with sputtering and hesitating. it started to happen when it was really cold outside and i assumed it was my tune (TTP-Engineering) reacting with the cold. BUT I'm not so sure now. I can't log anything cause my laptop is crap and i can't use anyone elses. i dunno how to describe the noise but bare with me here. this is from a third gear pull and this noise starts at about 3.5k and quits at 6ish. BBWWAAAAAAAA(4 grand) BUBBUBWAAAABUBWAAAAAA and it goes on from there. there is a noticable drop in power or a "Stutter" if you will. Any help?
