Bill I just have to say I love your tuning.
Recently I drove to Denver 225 miles each way using one fill up for the round trip my math says 25 miles to the gallon average for the round trip
. I though my math was wrong, so this past weekend I did it again and the math said 26 MPG on that trip
. I know the 60 miles of down grade each way that I am completely off the throttle have something to do with it, but dang!
there are 2 major passes on the way, one of them is an 11,000 ft pass called Monarch. Comming off of Monarch I have more than 20 miles of coast going either direction.
For those that don't have my truck sheet in their file: 97 F250 5 speed 4X2 California edition (split shot injectors), DIY intake, 3.54 rear gears, no propane, no water/meth, and a driver who was going easy the whole way using 80 daily.
