I'm having trouble this summer with my Fury lean surging when I get above 2500rpm and light throttle. I haven't had a chance to log while driving down the road, but I haven't changed anything in the fuel tables for some time in that area so unless the gas has gotten 'worse' or it's moved from E5-10 to E15 I'm at a loss? Anyone else having issues this summer?
