car won't boost past 7 lbs.

- Mon Jul 06, 2009 2:10 pm #128616 i'm sure this is some noob mistake on my part, but my car won't boost past 7 lbs. as soon as it hits 7 the car feels like i'm hitting a brick wall. i was trying to up the boost to 8lbs. but it wont get there. right now i'm running 6.5lbs. and the car runs great. any advise on what the problem is? thanks

Women... :wink:

Yeah, it's definitely a fuel/tuning issue, I would get that resolved asap, and try not to get into boost too much until you do :(

ya 308hp and has no dyno. i dont think i would lose my sheets if i had a car running that much hp. i would want proof. and a b16 with turbo and no other upgrades?! and if yourcar needs a tune/dyno to run right why is it a problem. if your car had alingment issues but runs fine do you just say it runs fine whats the point? lol but i would get it tuned properly. just gonna cause some more problems down the road..
