Renntech tune mpg

Hi! Just wondering if anyone with a RENNtech ECU tune could tell me what kind of gas mileage they get? I’m getting right at the 14 average city driving, but I’ve heard the tunes get better gas mileage even with the added power.

RENNtech dyno tune here, usually see 12.8-13.7 mpg in normal city driving.

I average 14 driving purely in comfort and not really getting on it. I get about 19 combined between city and highway. My car is completely stock though.

I think it depends how much stop and go you have to do. Mine does 12-12.5 in regular days and 13-13.5 in days when kids are on vacation and commute traffic is light.

No question, when I drive to have a little fun in normal city traffic mileage can drop into the mid-10's and that's not going over 45mph.

by Bay Area i'm assuming SF bay area...if so, even the simplest roads have a 1-3 degree incline. that little bit really is why mpg for us is never as good as people elsewhere.
