    after i figured out the charging system issue, i road tested the car around the block. for some reason under load it jerks and boggs and has completely no power. idles fine and revs up fine. im in second gear, press the gas to accelerate about half throttle and it'll bog and jerk the boost gauge doesnt go past 0. i checked timing and its set to 10degrees. anyone ever have this problem?

    Fuel filter blocked
    or
    Plug gaps too small

    I am currnetly experiancing the same or a similar problem,

    When the engine is cold and it get to about 2500RPM this happens to me. However if i let the engine warm up before driving its not a problem.

    checked for boost leaks and found none. i pressurized the intercooler system and no dice. i did realize that the fuel was very low and its gas that was in there for over 6 months so i'm gonna try and put gas b4 anything else.

    yeah try gas
    also if u dont know how good the plugs are replace them, thats cheap
    fuel filter could be clogged
    my car was like this when i set the timing back to stock 10 degrees, so i set it to 15 and it was fine.

    ok guys,
    NO boosting a cold motor unless you want a new one.

    Thanks for the Tip Mafix, I only tried to drive it cold once when i was running late.

    after i realised it was a cuz the engine was too cold, i let it warm up. guess i am just a Turbo n00b
