does anyone know how to tune up tom's toyota supra we got it to go 375 kph on the test track and it was running 11's on the quater mile but its stays in first and second way to long it just kept redlining in 1st and second for about 3 seconds and the rest of the gearing is pretty good.help?

What you have is a traction problem. Try turning TCS on and setting it to a fairly low number, like 2 or 3.

thanks, will do

but could u suggest some good ratios for 1st and 2nd

Hmmm...I'd have to sit in the car for that one. You could probably do four things though.

1. Make them taller. This will reduce torque in the gear and (hopefully) reduce wheelspin. This will probably make for slower acceleration however.

2. Make them shorter. This will allow you to go through them more quickly. This is probably not the best idea, as you'll have even more wheelspin then before.

3. Start in a higher gear. If you use manual transmission, start in second or even third gear.

4. Use the TCS to eliminate wheelspin.

You could also use the Manual Tranny and shift on hitting Redline.
If your Supra is with a lot of Hp (over 750). You will have to shift quickly.
You might also check your LSD settings.
As a baseline set your Initial to 5, Accel to 30, and Decel to 15.
The front of the car should be about 2-3 clicks lower than the rear to aid wt. transfer. Probably 5-7 clicks for drag racing (the 400 and 1000 meter).

or you could just use some skill and not put the pedal to the metal
