    My best numbers last night

    So i have a 04 gto A4 with ported and polished throttle bodie, pacesetters lt headers no cats, cai, 3500 stall with tranny cooler, stage 2 tranny with shift kit, drag bags, and a pair of nitto's 555 on the back, 160 thermi, and a speed density tune. My thing is do you guys think my car needs more timing and spark on the top end.

    reaction .4252
    60ft 1.8
    1/8 et 8.3
    1/8 mph 82.4
    1/4 et 13.00
    1/4 mph 103

    I thought before the stall and tune i was trapping 108 but i cant find the slips what do you guys think.

    Your MPH seems a little low for the mods you have. My car's MPH is 107 and I don't have as many mods as you.

    last year completely stock I ran a 13.7 @ 100mph. all season 245s and spun off the line. I'll bet your stock time was close to mine, maybe alittle better if you had good traction.
    heads, cam and better tires on mine now so I can't wait to hit the track this year

    stock for stock our GTOs are alittle heavier than the F-bodies, so you should have been slightly faster

    My tune gave me .3 and 3 MPH in the 1/4.....If you think your car is slower after the tune I would talk to the person or shop that tuned your car.

    true, just the stall should have got him to 103+mph.
    its the stock 108mph that sounds wrong to me.
    I'd like to take a look at his tune.....i wish we all had hptuners lol

    Well if you have hp tuner then your in luck because my tuner is a good friend off mine and he could post the tune so you can look at it. http://www.hptuners.com/forum/attach...6&d=1241803696

    your advance looks awful low at WOT, should be running up closer to 25-27 degrees instead of only 19.
    also looks a tad rich, I try and keep mine at 13:1-13.2:1

    remember too that you'll lose trap speed with the stall. 108 seems kinda high to me...that's a 12 second trap speed.

    the trap seems a little low but not by much. your stall is going to cut into your trap speed but should lower your ET.

    A 108 trap would be a pretty darn good trap for an A4 with your mods, Hell I'm only trapping 110 with a cam.
