OK, if the INOA says so regarding intro to the production line of superblends. Nothing wrong with a combat engine once the superblends are in there. There's no reason to detune it. It's fun the way it is. Mine now has 45,000 miles. After going from a combat to a '73 750 high compression I was disappointed in the '73s performance. Next time I was Commando shopping went back to another combat.
