..you won't find any other performance shop like Cobb Tuning,(beside Shiv's, heard of his good reputation also), Trey Cobb is that kind of person that represents all his products and does deep research before offering any of them. He is getting more busy each day, so don't loose time ,call hin, make an appointment and start enjoying your car like I do
Sen: you better check your "but dyno" there is no way with heads and cams you can't feel a difference
