You are so into the sound and power, that you keep flooring it. Try this: Drive like there is a cop behind you and you have warrants for your arrest. Watch how the exhaust helps you out at least 1 mpg at minimum.
I've learned on my Mustang, on my Mark VIII and a few others. Stay off it, be nice and watch the MPGs rise.
hahaha, try that and let us know if it works, I have my doubts though.
