I don't think these are the advertised 4.9 injectors. Bought these for my '07 Roadking with 96" engine. Engine has working cams, high flow exhaust and air cleaner with Power Vision setup. Map was sent as advertised for these injectors (4.9 gpm). After flashing the ECM with the new map the bike didn't even idle, flashed the original map before replacing the injector and the bike works fine not quite sure what the reviews are for them but a trip to the dyno tuner cured everything.
