I just picked up an 08 gt. I've gotta say, this is one of my most favorite cars so far.
I live in Avondale, AZ just west of Phoenix. If you're in that area and see a really loud g8 and it's orange, That's me.

I have an E-85 tune on it right now, but getting ready to go back to a 91 octane tune. There's just not enough corn stations near me.

I just saw your post. Nice G8. I'm curious if you've ever recorded a gas mileage comparison with the 3.27's against the old 2.93's (original gears if I'm right)? I'm just curious how much it might have dropped? Did you disable the DoD too? I didn't see a cam change n your description. I want to improved my GTs power but I want to try staying with 87 octane. Just trying to maintain as much gas mileage with gaining as much power as I can. Gears add a lot of performance without affecting the motor but I wonder at what mileage cost? Thanks for your input.
