After putting in a CAI, super chip, and redoing the exhaust, what are the next mods I should do? Preferably cheaper mods that add more horsepower.

Adding rear end gears won't add more H.P. but your engine will rev quicker.Cost including gears is around $525.00 installed.

FYI. I know it is proabably a freak occurence but a member on this board said that his clutch exploded and when it was in the shop they would not cover under warranty. Blamed it on switching out the gears. Too much TQ and the clutch gave out. Like I said proabably freak deal but this is a mod that you can't switch back to factory very easily. 2 cents.

Fairly inexpensive mods that will ad horsepower are a 62mm throttle body (about $400 and adds about 10 hp), a throttle body spacer (about $70 and adds about 10 hp), ceramic coated headers (about $400 and adds 10-15 hp), or underdrive pulley setup (about $250 or so and adds about 10 hp), and if you are really crazy for HP, a supercharger (about $5000 and adds about 150 HP....okay, maybe not inexpensive, but damn cool).

TB Spacers wont add 10 HP 2-3 max.

i'd Say UNderdriver Pulleys, Electronic Water Pump, Charge Motion Delete Plates, and get a SCT Tuner

What he said, along with a good set of headers and catted or O/R pipes. All this, you should be well over 300 rwhp. :thumbsup Oops, never mind, just saw in your signature, you already have the headers...
