Hi, I have a highly modified(heads/cam/ported supercharger/meth/flex fuel etc) C7ZO6. I am not having any luck with some well known local shops. My part throttle driveabilty is bad(hesitation/bucking) and WOT is pig rich. I have wasted a ton of time and $. I need a top notch tuner that truly understands these cars and is willing to figure out my tune and take the time to do it right. Alot of shops claim to know what hey are doing but most of it is BS. Please any ACTUAL good shops either local(near Philadelphia) or willing to do remote tuning please let me know
