if you're going to buy a tuner, then don't get a mail-order handheld tuner. if you're going to do it at all, then do it right and get the Sniper Special Forces tuning software. you can find it for around $400-$450 (contact the guys at Hollywoodracing.net, Mathew hooked me up and their customer service is awesome), and it gives you much more end-user adjustability than a hand-held, and it's very user friendly. you can use it to set up a base tune and then as you add more mods, just go in there and fine-tune it by telling the software what mods you have on the car. and once you learn more about tuning, you can tweak it by making adjustments to the timing and a/f mixture at different rpm levels.
