weird mpg problem
If I fill up same pump same station all the time.
If I fill up at 1/4 tank I get 18 MPG
If I fill up at 1/2 or less I get 14 MPG
Both numbers are hand calculated. I have a RR, intake, exhaust, HPX, DP Tunes (80 econo). I can do this over and over and over and get the same results every time. I have drop the tank and put a new pickup tube without the bypass. Pre liminary fuel filter oil and fuel air filters all new.
Anybody have any ideas why the weird mileage? I assume I'm sucking air somewhere. The RR should take care of that right?
