There is a guy named Will at Overkill that can tune those year cars, but its a canned tune you can't change anything after you get it. He somehow cracked them or something and figured out the gas gauge issue.
Easy way to do it yourself is to buy an 04-05 pcm.

Doing it myself with an 04-05 PCM would mean a backward working gas gauge and I heard a few other dash issues, is that right ?
Also is there any performance shift mode for a GT? Mine does not have the Tapshift and the car shifts really early, similar to my GTP when not using performance shift mode.
