Engine starts great and seems to be running on all 6 cylinders at idle but is a dog on the water when under power. Replaced power packs, triggers switch, efi module, return line fuel filter and no luck. I'm ready to deep six the port engine at this point. It's derby season and I have an anchor on the port side.
Max rpms while both engines WOT is 4000 on port - 5200 on starboard. Any ideas or advice?>
