phantom xr6t, what's yours like at midrange and top end? Mine is mental at mid and top end and can put you sideways between 1st and 2nd gear changes on dry road unless you are driving perfectly straight but so piss poor off the mark it's embarassing, what tune have you had 10 psi ,generic ,custom,what rwkw's? cheers for the reply, the fact that your car is trying to break traction sounds like you are right on with your tune. I just got back from the shops and mine is pretty lifeless until above 2,500 rpm.
