    Same thing my buddies 99z was trapping. Averaged 101 and hit 102 once. Also hit a few 98s, 99s and 100s. His was stock but with a muffler on it.

If you forget about all the internet BS about cars, you are right were you should be at a 305 flywheel rating.
    305 flywheel is underated

    ohh really, thanks for the news . GM has proven its lack of consistence with the F-bodes and Corvettes. They dyno all over the board and run at the track all over the place.

    His car is run exactly where it should be, I have seen tons of that year of car running the same times. Autos of course though.

    It looks like they didn't correct to sea level numbers is all, that's why it's so low. Corrected you would be 280-285 which is obviously correct with your 1/4 times

    2000 Camaro Z28

    i did 13.5@102 with a stock 2000 Z28 A4 (not sure of the ratio)

    After MTI clear lid K&N filter, blue MAF ends it did 13.3@104

    I saw a 2005 GT that night and it did a 14.2@98 It may have been a automatic
