American Nightmare

So I have an 02 GT Auto with a K&N CAI, Magnaflow cat-back, and soon to have a shift kit installed. But I'm wondering what should be my next step. I'm considering Steeda underdrive pulleys, and possibly a larger throttle body though I'd wonder if it would be running too lean. Any suggestions?

Gears, should of been first mod.

xx10Gt

Agreed. Then maybe a tune for the car

American Nightmare

Any particular brand? Will they decrease gas mileage noticeably?

uberstang1

Yes 4.10 gears and a bama tune, you can get everything here on this site, go to the vendor section and go to american muscle. They have the best price, the fastest shipping and you get a discount for being a member here, oh yea also you get FREE shipping.

Cool, I didn't know about the discount. Guess I'll get those 4.10's and that tuner.

Now I've heard two different stories or ER opinions, 4.10 for an auto, 3.73 if you have a manual. Any truth to this ? Or just preference?

No not really. The higher the ratio, the lower the top speed, but the faster you switch gears, I generally like 3.73 for a daily driver.
