Best bang for your buck for tune up is going to be the underdrive pulley and lightweight pulley kit. Also, get a CAI... doesn't matter which one, they all help. Get rid of the stock exhaust manifold and muffler too. I put a Megan racing header (online from ebay was about $100 plus shipping) and the 3-A racing muffler from Autozone (yes, I know, it is cheap) made a VERY noticeable difference in how quickly my car revved up. They help with fuel mileage as well because the car doesn't need to work as hard to do the same amount of work. Get a good injector cleaner, stick with the Iridium plugs, and check out the Royal Purple transmission fluid to help with that. Those are my recommendations. Take them as you want.
