Don't forget a tune-up. That is a necessity. Some Belden 8mm wires are the new thing. Lifetime warranty... and like $30.
The TPS mod and MAF Screen removal are also good. I did the TPS mod 20 miles before my car'* 'resting period'.. and there was a big increase in throttle response.. she used to take a second to go from idle to WOT, and the TPS mod fixed that.. I don't think I went faster
.. but I would suggest doing it. Plus the MAF screen removal, I could feel the difference in power in that.. MAYBE 5hp... but mine was kinda bent.
A good cleaning of the TB and IAC, and IAC Passage would be good, too. A can of seafoam engine cleaner.. 50% in the tank, 50% in the PCV valve. Does wonders.. I currently have my top end off, and everything seems fairly clean [for it'* age], and I think some [if not most] of it has to do with me using some Seafoam.
If you do the CAI [Cold Air Intake].. alone, I would switch to one heatrange colder plug [I like NGK.. so the TR55'*].
And even little things, like keeping your tire pressure at specs, and cleaning out your trunk will help you go faster. It'* the little things that count
