I have FLSTC 2013 with adds--Vance Hines long bigshots, Roland Sands heavy breather, 254E cams and SE race tuner. Bike was dyno by HD dealer when parts were installed last year. It runs good but rear cylinder kicks out very often in traffic. I live in Texas so it is hot here. An indep. shop here say's it is running to lean and dealer will not tune it rich due to EPA. So he say's that I need an add on tuner. Is he right and which tuner do I get. HELP!!!!!!
