I'm running the gen 3 on my 2012 dyna switchback . I have a stage 1 breather with a vance and hines slip-on and the cat drilled not removed. The bike was still in the break in period when I added the gen3 . I got on the first tank 36 mpg the second tank 37 mpg and the 3rd wasat 38 mpg. After installing the gen 3 i jave run 4 or 5 tanks of gas and I am getting 34 mpg. This is my current setting from factory grn 3.5 Ylw 2.5 red 2.5 grn/blu 2 ylw/blu 4 red/blu 4.5 i heard that backing off the grn by .5 and taking the ylw/blu up.5will help this sound right?
