Default Smarty JR MPG

Just got home from my Colorado trip.Before I left I loaded the 40HP mode. I make this 2000 plus mile trip once a month so I can compare the same route each time. Before the JR the best I got was 16MPG. This time I averaged 17.8MPG. I tried to maintained 75MPH at 2100RPM. This was up into Breckenridge area and back to Iowa. Breck is at 10,000 feet so I had a little more smoke at that altitude. Very happy with the milage. I have about 26,000 on the truck so it still isnt broken in yet. When I had my 99 as soon as I hit 60,000 miles my mileage jumped 2MPG. This spring I will be pulling the 25'GN with equipment on it. I can't wait to see what my milage goes to with that load. I will try the 40HP first then the 70HP. Before the Smarty I got about 9-10. All hand calculated. My overhead is consistantly 2 MPG high.

Default RE: Smarty JR MPG

I got best mpg outta my jr. w/70HP I got 18.6 hand calced but I was also running 85-87mph I tend to get best mpg at 65-70mph the lie-o-meter would get in and around 24mpg and its usually off 2mpg from hald calc, so I figure 20-22 on 70 hp...
I wanna try the 100hp on it but would like to get some driveline upgrades in it before running it much, I can't afford an unwelcome breakdown [&:]
