I thought the 1800-2200 range was best for launch, or is that just for the Auto/SRT folks? I havn't been to the track but I don't think I have honestly tried to take off any higher than 2500 unless i wanted to make a lot of noise or get a little sideways.(considering max Tq is at 3k going over that would seem like automatic tire spin to me...) I had a blowout on I95 a couple weeks ago and just got new PS2s put on the car. I launched it just over 2000 and there was no spin at all and it felt almost perfect to me. I would assume the track would be a bit stickier than regular roads but not 2k different. Did you have a lot of spin? and which tires are you running? I wonder how much it will take to get the N/A into the 13s... I would be happy with high 13.
