Tune? What tires did you have? Consistently running different or just one run at each time because a lot of it is in the launch.

17 205 40 17 I think , but I hooked up fine like I did with the 16.1 .. My bottom end seems slower

No tune

Run it again. I did 16.with injen intake, 2.4 tb, and custom full exhaust. Didnt have header in at the time, and the header made the car feel alot better and more responsive
