Adjusting air/fuel mixture. When you get the nitrous installed, the shop will make all adjustments needed to run.

Should work fine. Its still a 8.8" rear-end. But I wouldnt buy used gears...and also go with 4:10s you will like them alot more (from what I hear).

ok thanx i cant make up my mind i want 4.10s but 65 bucks for 3.73 is not a bad deal

yellowgtstang18

is there any places where i can get 4.10s and a tuner together for a better price

You need a tune, need to use the proper plugs...

Anyways, $500 or so for a gear install with everything isn't horrible.
