I really honestly think my tranny is whats killing me. The thing is shifting like an old lady. I'm running stock gears (3.08:1 with the limited slip) so gears would help a bit. I think a good tune, including shift points/firmness would do a world of good, that or just a full tranny swap. Another thing to keep in mind on my 60 foot time is I'm launching from idle most the time. Working on loading it before launch, but its a bit hard than it seems...for me atleast.What do stock '99+ GTs run? I doubt its near the high 13s. I very much doubt just a PI swap getting anyone into the high 13s. Just a guesstimation, but it'll take our car approx 250rwhp to run in the high 13s. Assuming my cars is running correctly (which it seems to be) I should have slightly more HP than a stock PI car (based on the increase in CR). They are rated at 260 fwhp, so lets call it in a automatic with a 15% loss to the wheels 221 rwhp. That would put me about the same. My car weighed in at the track at 3380 w/out me in it. Honesty don't see why 15.007 is such a horrible time, that seems about right to me. I'm still learning here, so if there are flaws in my math, please educate me. 14.6 is a great time Void, dont know what your doing right, but keep doing it. A good tune, like I said, will open up alot of potential.</blockquote>
