Get rid of the K&N intake and get a Halltech.
The transmission on the M6 wasn't designed for a 4000lb car so its a little tender. Make sure you turn off the traction control when your doing hole shots. Tap it once and the traction control goes off. Tap it once and then hold down on it for 7 seconds and both your traction control and stability tract go off. Tap it twice and it goes into competition mode(don't do hole shots in competition mode)
