Factory Mileage readouts - Are they accurate after instalati

Post by BigRich »

I have had my Diablo installed and loaded in my Dodge 3500, Cummins Diesel. How accurate are the readings on the factory overhead readouts panel? Or are they accurate after Diablo is loaded? My reading says 39 miles per gallon average. Before Diablo the readout was 22 mpg. HELP Please!

The factory computers are way off from the beginning. Best way to figure out your mileage is to hand calculate it. Sometimes my overhead will read 26-27 mpg but I'm actually only getting 17-18 mpg.
