Finally had a chance to run my car on Saturday. The car has a Procharger P1X with a Circle D converter. It's supposed to be a 4000 stall. I tried leaving at 1500 rpms and it only did a 1.62 60' and on my second try I tried leaving at 2200 and it only went 1.65. The second run had to be aborted as it would not make the 3/4 shift. The first run it was 70 degrees out and the second was 77 degrees. Just trying to find out what other people are doing to get a better 60.
