In 2nd or 3rd gear at 4k rpm hit the gas and car stumbles and back fires, but if I ease into throttle then hit it it is ok...........
or if I stay out of boost and take RPMs to red line and let off suddenly it sounds like I have a turbo blow off valve then rattles........
I changed plugs, cleaned MAF sensor, changed fuel filter, double checked tune, and I am at a loss, can't hear anything at idle car is too loud and even louder at RPM or at speed.
I have the full bassani exhaust headers, X-pipe and CB, I think it is the slip fit collectors............................. any ideas or help would be great!!!
