I am no authority when it comes to tracking these cars. But 12.9 with meth seems slow to me. As I recall my car ran 13's with a busted tranny. Maybe the DA and all that is having a great affect, so is there a way to calculate wht your times would be in better conditions? Or maybe local people to you already understand the effect of bad conditions for performance there.
Another consideration, add the ACES IV. Then load the 93 octane tune. It is a WORLD of difference better than the 91 octane tune.
Also, do you have your audio upgrade pix on here somewhere. Would like to see it.
