hi, im new to this forum and was wondering how to get more power out of my 07 gt. already have factory headers, throttle body spacer, custom tunes from Bama

 

Welcome, I moved your post from the V6 section to the GT - be sure to look at where you are posting so it goes in the correct section.

Throttle body spacer isn't doing anything for you but add weight and lighten your wallet by the way. It isn't like the carburetor on these cars with fuel injection.

 

factory headers???

 

If you aren't planning to go forced induction, some simple bolt ons will get you on your way and stay well away from BAMA tunes. Here's some useful reading for you:

However if you DO decide you're going forced induction, forget all of the above and save your pennies.
