How much milage can expect to lose by running a brenspeed 92 octane tune compared to the stock tune??

Normal running arround ( drove it like I stole it) I get arround 17-18mpg.

When I drive it like my wife would, I get 20-21mpg on normal day to day driving.

On a road trip I get 26-27mpg cruise set on 70mph.

Your thoughts?:feedback

Oh and as an FYI my car is an 07 gt 5spd with the 331 rear gears.

Actualy I would say quite the opposite. Usualy a good tune will result in better mileage(to a certain limit). Tuning the timing to burn all the fuel properly equals more power thus equal less throttle required to get said power thus netting better mileage.

Zip gets about 25mpg on the highway with a Bama race tune, that's down from 27with the torque tune.

Man I have been looking for a damn gto since i got my car back. I did get to hand a camaro his ass today though. Need a little more than exhaust to run with this ford bow tie boy.

Oh gt33, your talking straight city miles, im probably pretty close to you then becuase im averaging about 17 and i do a lot of highway.
