Right, the speedometer was 7mph fast when I did that last one. I spent about an hour messing with the tune Sunday morning before the race. It's right in the money now... Plus I changed the tune 5 times at the track adding timing and changing the shift pressures trying to eliminate the trans slip when shifting... I just ran this with the current tune.
I bet if I Check it in hptuners it's a 4.0 or 3.9
