Need Power What Should I Do Next? Thanks

[ewalker302]

First off, here's what I got. 1990 GT Auto, 3.55 gears, Stock size tires & rims. 100,000 Miles, Runs Like new, No problems to fix.

I have Installed a Mac cold air kit/K&N, H pipe 2.5 w/o cats, but all other exhaust componens are stock.

I have set the timing correctly and modified the throttle position sesor correctly, removed the screen from my mass air flow meter (should I?). I have also recently replaced rotor, cap, wires, belt, hoses, tires, plugs, struts, shocks, and rack & pinion unit.

Now Im looking for a little more kick in the pants. This is car is a daily driver in south Mississippi (very hot summers).

I'm more interested in all around performance, and power than ETs. I dont want to have to get into gearing, or transmission mods.

Here's what I'm considering:

1. Larger throttle body (size?)
2. Larger Mass air flow meter (size?) I could hone it myself, but is it worth it?
3. Underdrive pulley kit. I run a moderately sized stereo sytem w/amps, and it gets hot here in the summer, my ac blows almost to cold now so the ac pulley does not bother me. I'm only a little worried about slowing down my power steering pump because of the in town driving I do. I understand that they are supposed to increase the life of your accessories. but are they worth it for someone who is driving their car everyday?
4. Cat back system, it would give me 2.5 pipes from the stock headers to the rear w/o cats.
5. Triangular Strut tower brace (basic). Will I be able to tell a difference in everyday driving, or only when I am really carving a turn?
6. Computer mods (chips). From what i've heard they are'nt really worth the money, but what do you think?

Unless I hit the Powerball this week, I will most likely be installing components one at a time, What should I do first?

I apologise for the long post, but you guys know your stuff and I know I can get real answers from you, and not a sales pitch from some guy behind a parts desk trying to rip me a new one.

If you have the answers to any of my questions or advice about parts I can install myself that I have overlooked, please help I appreciate it.

Oh yeah my buddy has a 94 camaro with a sequential port 350 stock, but just rebuilt. I am itching to give him a good view of my gt's taillights.
