I have a 2000 gt and i would like to buy a tuner i jus dont know what kind

 

I would recommend either SCT or Diablo. Look at both, see what parameters you will be messing with and which one fits you best, then buy it. I would only recommend Sniper tuning if you know what you are doing around a car and engine, otherwise stick to the canned tunes. You will also want to go to a local performance/dyno shop that you would use and see what they program for. If you don't have their tuner, either 1. they will charge you more, or 2. you will need to buy a second tuner.

 

btw don't post the same question in multiple forums, its a waste of space
