Mid 13's? what HP are you running?

What was your 60ft on the 14.44 and what MPH?

Try dropping the front tyres down to 15psi... warm them up and then give it the beans. Im a regular up there. Love drag racing. Im 25th in the street challenge currently out of 130. I wont get any higher cuz i am not modding my car anymore.

Reducing the pressures increases the traction. Nothing really to do with power other than getting it to the ground quicker.

Reducing the pressures does work to a poitn but I would have thought 15psi is waaaay to low. You want the maximum contact area on the tarmac. Too lower pressure and your just running on the sides. Top Fuels run low pressures but they have drag specific tyres.
