Today we have this Mustang GT here that has a Cobra motor installed and a Kenne Bell Supercharger. It also has the Cobra front clip and rear bumper installed. Customer was experiencing several driveability issues. We found there had been an improper tune installed and the handheld device which the car was orignally tuned with had been long gone according to the customer. We have sourced a new SCT handheld tuner and are now in the process of creating a tune file from scratch. Gotta love that supercharger whine!
