Gas tank discrepancy

x3.....Usually 26gallons gone when the light comes on. The most I ever had to put in it was 29 and some odd gallons. If you are doing long hauls or towing and have LARGER than stock tires pay no attention to your computers calculated gas usage. Its going to be off. Mine is always within a gallon but it gets way out when towing the boat on long hauls through the mountians.

yeah I corrected with my Diablo Programmer ... So my computer is calibrated to 35" tires. Its pretty damm close, when my fuel usage meter says 22gallons used ... It take 22 gallon to fill up. Just the travel mileage left on the gas tank is off big time...

At 22gallons it says I have 38miles left on the tank ... And if the tank is a 32gallon tank that still leaves me with 10 gallons. Either way, with the programmer and adjusting how I modulate the gas pedal; I've been gettign 13.2mpg instead 11.3 mpg before...
