For those of you with the Gt Automatics,Bamachips or Brenspeed tune and intake.When you stomp it off the line,How bad does it spin and will it bark the tires going into second gear??

I have Evolution Performance tune and with the stock tires it would melt the tires and yep I can bark 2nd gear. I have since put on a 275 Sumito tires and it dosent spin those near as bad. I was at the track and my 60' times were in the 2.0 range where a stock tire would have been 2.1 or a 2.2 At the track I was leaving at about 1800 rpms....any more than that and it would spin'em. but a 2.0 is pretty good for a street tire.

I have heard many people that are very happy with the Evo tunes rguarding shift points and firmness.
