My car weighs 3830 with me in it. I'm going to run the 1/8 again this weekend at a huge car show/race this Sunday after the show on Sat. Since the motor now has 3000 on it I finally decided to change and check the plugs. Since Cal tuned the XFI and the car made outstanding power I felt there was really no need, well, the gap was set at .040!!!! So, that answers a couple questions and adds a couple. Wonder if it'll run any better this weekend then my first time at the track? Also, my first time out I hadn't checked the tire pressure, they were at 32!!!! I'm excited to try and get a 1.50 60ft or better!
