    Re: Fuel mileage

    I think part of my issue is by the time I get into 1600rpms I'm going~78 and is causing more resistance if that makes sense? In the Spring time I will drop back to 33s for a bit and see if that doesn't change my fuel mileage. Around town I can actually get into the 16mpg range driving nice and not hitting a light every block or so.

    Well I did take the same trip this morning as last week. I ran only the 150 tune and set cruise at 67 mph. Rpms still low for my liking at just under 1500. Avg 17.2! I'm pretty dang happy with that.

    Re: Fuel mileage

    Question when pulling flat ground and pulling weight what kind of rail pressure are y'all seeing? I'm seeing 21-22k , pulling a hill will bump to 24-25k with stock tune. Any increase in power tune will cause boost to be easy above acceptable range
