I was running 13 psi in the rear. They seemed to hook up pretty good this time, last week I was running between 22 and 18psi and was pulling 2.0 60' but it was also hotter last week. Any idea what to check for with my trap speed? Congratz on your run last weekend, I saw your timeslip and mine looks faster upto 1000' but you times after that were better then mine and your trap speed was almost 4mph faster. Is it the NA rear or ya think something could be wrong w/my top end? 60'=1.93 330'=5.42 1/8=8.35 MPH=87.3 1000=10.82 1/4=12.92 MPH=106.8
