I'll try to keep it short. Installed dual head pipes and a Fuel Moto PCIII tuner w/aircleaner. Tuner came loaded with map per my specs on pipes, a/c, etc. Intermittent stumbling at warmup and at hot idle. Quit completely after slowing to pull into a gas station. Restarts and runs perfectly at speed and all rpm ranges. 2008 RG w/TBW, reset with the 3 cycles of ignition switch method. Checked new intake gasket, retorqued exhaust flange nuts, checked battery terminals. Bike has been garaged with 100% full tank of fuel with Sta-Bil added. No issues until I made the mods. I've got a note in for Jamie or Keith @ FuelMoto, but thought I might get some input here. Thanks.
