i got an 03 gt with just some bolt ons. im looking to get a programer. are they worth the money and if so which ones are better and where can i find them?

 

SCT or diablosport... either one is really good...

though most tuners use SCT

you can get a bank chip (piggybacks on your current ECU)

or a programmer (overwrites your current tune with a "canned" or pre programmed tune)

 

+1 on either SCT or Diablo. Though you only have bolt ons right now, if you decide later on down the road to go FI or any other engine work, you have the ability to tune your car with the SCT or Diablo for those mods.

 

A cheaper alternative on the SCT route is to get the 4 bank eliminator from americanmuscle.com

You can get it preloaded with tunes (4).
