u7130 worse fuel economy?

i run just the power puck on the high setting over head says 19-20 mpg , hand calclating itr comes out to 17-19 .

it actually was better with the tow tune. I dont trust the overhead computer. If the the over head was accurate i would get 25 mpg, I wish!! The 2 1/2 better mpg was in comparison to the eco/perf tune. For me that was the better of the tunes. Currently my mileage has dropped a lil, mabe a new filter is in order. By the way I was haveing an intermittent miss while cruising, I think now that some how I got a tank of Bio Diesel or some serious s!@# in the tank. It now is finally running miss free. I now watch the fuel coming out of the pump to make sure its the light green it should be and added a locking cap. Hope that helps
