Let me start with a little background. I had an 03 Cobra from back in the day. Kept it till around 3 years ago. Picked up an 11 GT500 last fall. Decided to start the slow modding and picked up with the tuner that did my 03. That was a huge mistake. I have had around 12 tunes from him and only one has worked. In that time of messing with him I put on the 2.5 pulley, off road X and such....the simple bolt ons...He never could get it right, car would fall on its ass, and I literally started hating the car and modding it....I really wanted to pull the trigger on a VMP Gen II but was scared to because of the tuning issues. I bought the blower (thanks to talking to Alec with VMP) and decided to have a local guy dyno it. That was going to be an extra $750.00 for that. Really didn't want to spend that extra coin so I called BJ at VMP to tune it. After talking with him I hired them for the tune. Today I got the tune/downloaded it and all I can say is:Wow The thing is a beast now. The tune is spot on and runs like a striped ass ape...Thanks VMP for great products and a great tune. CUDOS to the fullest!
