dyno numbers for 06 GT

With a good set of headers and H pipe I bet you will be over 400. The factory exhaust manifold has a very small outlet, about 2" and lots of casting build up making it even smaller. At least in mine there was until I ground it out.

tunes with mods

so i have a question for you guys, since i am new to tunes (i am an ASE certified tech) i know everytime you mod something you need to tune to make it work properly, but say you install something like an X pipe and get a tune, now you have a few more bucks so you get a CAI, you need to retune. my question for you is how much does it cost to retune, or if you buy a tune that comes with a new part how can you incorporate the tunes, i know they are not cheap. please enlighten me
