For those who installed a new tune and CAI, have you noticed any increase in MPG? If so, what are the numbers?

to be honest with you, i shut off the MPG info center about 1 week after I took delivery of my car. its a sports car. it has allot of HP, its not a smart car or efficiency vehicle. if you wnat to truly save mpg with the gt500, then stay off the pedal....not trying to be a smart alec at all....

Well, quite honestly it's worse, I think mainly because once you feel the power you always want to be on the pedal!! But who cares mileage is not a concern for me or I would not have purchased a GT500 Then again it is not a daily driver, just a pleasure machine for nice days and spare cruising time!!
