What is the next mod I should get for my 2006 mustang GT?
I currently have 3.55 gears (the reason for this was to get a little better acceleration, while still maintaining good top end speed+MPG) 40 series flowmaster exhaust, cold air intake and that is it. My budget is around $800 including any labor, if needed. I was thinking about NOS? I want the most TQ and HP that I can get with this money. Please be detailed with your ansers, including website or acual product name...thanks
