Well when your sitting there Idling for 10-15 minutes you get 0mpg. ZERO.
And I have to warm my car up twice a day. And the PowerFC runs my AFR at 12.8-13.5@1300RPM during warm up.
Let your car idle for 15 minutes then go drive with 1 gallon in your tank.
When you run dry, put another gallon in and go, dont let it idle for 15 minutes, and tell me you dont see a fairly large distance in how far you get.
Thats all I was saying.
Unless you dont let your forged pistons warm up before drive.....
