The engine has less than 2000 miles on it so its not even broken in, I have some tuning to do and more parts to put on.
My next major MPG effecting part will be installing a turbo "F-code" intake manifold. I will be replacing my prized "J-code" intake which as proven its self to be a good set up for fuel economy. The F-code intake will be put on so I can play with water injection and so I can install a turbocharger later on.
EGT readings tell me more heat is going out the exhaust compared to the old engine so I need to advance the timing a little bit. I had to track down a special tool to properly check the timing.
So far my highway milage was looking good at 21mpg considering I had the truck loaded up with tools and parts, had a 24 foot aluminum lader strapped to the roof and was pulling my trailer.
Being down 4 to 5 mpg compared to being empty with nothing on top or being pulled behind is looking pretty good. I also had brandnew 31'' yokohama AT-S tires installed right before my trip.
I expected my fuel milage to be in the high teens for that trip.
An aluminum lader has to be the worst thing you can put on a truck for aerodynamics, I could hear nothing but wind noise coming off that lader any time I got above 50mph.
