I have a 2019 Sgs have Arlen ness big monster sucker breather, v&h power dual header, krome works slip ons, S&S 475 cams, cam plate, oil pump, lifters, push rods and tappers and power commander tuner! Has anyone had issues with tuning with this set up? Seems you have to add a lot of fuel in the lower RPM ranges! Has some studdering in the 1800-2000 rpm range! Also what are your dyno numbers?
