I have a 2010 Ultra Limited 103 motor I have put V&H Big Shots, Sreamin Eagle cone intake for hard lowers, and a Sreamin Eagle Race tuner. I had it tuned and dynoed at the dealership where I purchased the bike and the parts. I have removed the hard lowers. I had a question about gas mileage I never checked the gas mileage before the mods but have checked it recentley and at one point I got 42 mpg and other times I have gotten from 35-39 mpg. Today I filled up the tank and I got just under 200 miles before the gas light turned on was on the interstate and going 70 mph at 2700 rpm with the cruise on 90% of the time and the rode was pretty flat. On that ride I got 37 mpg. I had a 2008 SG and it got 42-44. Is this normal because of the mods?
