I will update how it goes, but as far as fuel mileage increase it may be tough to gauge since this will be feeding my new engine build that should be around 550 horses which I haven't driven yet. Hopefully with it being self tuning and the fact I will be running 3.08 gears and with the changed 2.75 first gear in the th400 it will still get decent mileage while being a blast to drive. That's my goal anyways
