Upgrading 2003 gt
Just got a 2003 gt, which mods can give it some hp and do not affect the mpg or make it better?

Suspension mods wont affect you mpgs. Thats about it. More power equals more fuel.

You can do exhaust and that wont effect it much and an intake. Any power mods more then that you will see a change in mpg's

Tune can definitely make it better if you get the right tune.

I have summit racing coil packs. Better gas milage and far better throttle response. You can pick a set up for about $220
