Same scenario. My car is untuned and 8-9psi. My buddy has a 2nd Gen eclipse with a big 16g, 20psi, 272 cams, AFC, FMIC, etc.
went from 2 digs and 3 rolls. Same thing every time, I would jump out by two cars (yeah torque!) then it was dead even. I couldnt pull away and he couldnt catch up. He was pissed i had to show him my peak hold boost gauge . . . see only 9 psi! HAHA
