[QUOTE="Mineral_01', post: 10829858, member: 106289"] Hey guys, tried searching but found no exact answer. Anyway, I've got an '01 cobra with eaton supercharger and it has a surging or hesitation when letting off the gas on a hard pull and getting back into it on the next gear. It runs great under normal driving or soft pulls. I've read it could be my pprv or an IAC problem. My fuel system is a stock '01 tank with avaitor pump and 20A boost-a-pump which should be plenty of fuel for only 446 hp. right? The car was professionally tuned with more than a safe air/fuel ratio and 16 deg. of timing. I remember my tuner said he had to adjust the throttle plate screw (Accufab) to get the idle dialed in. It also has had a complete EGR delete as well. Could any of these mods have an effect on this? Some other specs: JLT CAI with 90mm MAF, 39lbs injectors Longtubes Off road H-pipe 10lbs. of boost NGK TR6 gapped at .034 Those are the only mods I could think of that could relate to my problem. Thanks for any help. [/QUOTE]
