I think the heat got you my friend. I did 12.7 before tune in 97 degree heat at 110 mph....did the tune to what I had at the time, it driopped me 2/10ths, to 12.5. I was stuck there until further mods. I am at 12.3 with a dual needswings cai...now, I will look at cooling mods. But, not for the roadster anymore. I know the roadster has a 12.2 or maybe a 12.1 in her, but my attn has turned to the new coupe. I will use what I learned on the roadster to maybe get the coupe to an 11.99 w/o meth....then we shall see from there...lol....good luck, but I think heat got you more than anything...
