Message My car feels like it pulls pretty good, but it doesn't really move that fast. I just raced a bone stock mr2 turbo and won, but only barely. We raced in 3rd gear and I was only about 1 car ahead when I let off. My car has a good bit of upgrades. (12psi, JWT eprom, Z1 SMIC, dual intake, 2.5" dps and test pipes, open after z1 h-pipe, lightweight flywheel and exedy clutch.) My compression ranges from 133-143 psi. I've done a boost leak test and found nothing. Spark plugs are good. Shouldn't my car be making ~330 whp? What things should I check? I was thinking of 2x checking my ignition timing. (Belt is correct) I also thought about getting a better tune, as well as dynoing it to see how awful it really is. I'm really at my wits end and i'd appreciate any insight. (Sorry for lengthy post)
