    ok but i raced my friend with a 00 GTP with the same mods i have and i put mine in 1st gear and he left his in drive, when he honked three times i pulled about 8 lengths on him. im not making this up, it was really around 8. and he asked how i took off so fast. i told him and he tried it but from a 55 roll so we were in 2nd gear, and it was a much closer race than with him leaving it in drive. i have a 3.4 pully, 180 thermo, plugs, msd wires, AC delete, and resonator delete. he didnt have the AC delete which i heard is only a 2hp difference

    That's because the stock PCM sucks for shifting some times. There are areas it won't go all the way down to first from third, but instead go to second which severely limits acceleration. Nothing a quick PCM tune can't fix, so you don't have to abuse your transmission to get it to work right.

    TORQUE FTMFW!!!

    Thats what makes it feel faster, increased pressure against the drivers body.

    Shift Kits w/ RMVB FTW!!

    Wonder if they make a shift kit for the GP....I havnt seen one yet but I dont even know what tranny is in the car, ive been lost the demise of the turbo hydramatic.
