What type places can I go to for a good tune for my '05 GT? I'm pretty sure the dealer won't touch it. And with these tunes, do they force you to have to use premium fuel?? It's kinda nice being able to put the el cheapo gas in. I already have another car that "recommends" premium and gets sucky mileage.

 

Where do you live?

I'm in Socal, here's my guy:

If you want to get the most out of any tune, Premium gas is required. If you ask for an 87 octaner tune, they will laugh at you.

 

I'm in San Diego and would recommend jbaracing.com.

 

Thanks, guys. I'm over here in Charlotte, NC. Guess I just need to start searching for some reputable tuner shops locally.

 

Good luck. Try to find someone whose been in business a long time.
