I went to Irwindale 4/23/09 and it was in the mid 70s humidity was 54% and heres the best run. RACE WEIGHT IS A HEAVY 5190 LBS RUN 1 - RUN 2 WAS THE SAME 8.16 @ 83.83 DA.......1475 FT 60'......1.76 330'....5.23 1/8.....8.16 mph....83.92 best ever The new tune Scott did netted me a gain of 7 hp and 5 lbs tq and the preditor update from 8r20 to 9r12 had to help.
