quick update for you koveleski.... jerry retuned my ecu by remote cable. awesome!! he mails me a cable i plug into my laptop and obdii port. then logg into a website and he can use my puter to retune!! (of course my pos puter didnt help me much! error booted off web countless times!) anyway after he turns on my O2 sensors , reset my fan settings, and reflash my tune im seeing 11.9 to 12.3 at 5800 rpm and 18 lbs boost. car feels strong pulls like a beast and no the afr's are in a safe place. retune highly recommended!
