2 Trucks Different Results

[thelastcion]

My father and I both on 07 Harley Davidsons. His is an F350 and mine is an F250.

We both use the Bully Dog Triple Dog. We use all 3 settings depending on the work load.

I can get upwards of 22 MPG at 75 mph and he can't get above 16? Does this simply speak to the fact that no 2 engines are the same? Or is there something that can be done for my fathers truck.

No other mods have been made to either truck, performance wise...

What gear ratio's do you have, I'd bet you have 3.73's and he has 4.10's which would explain the difference.

I would think the flash stategy is different between the F-350 and F-250. I'm not happy with my truck getting 15 or 16mpg ether.
