So maybe I need Bill to write me an 87 SUPER tune, and a 91 SUPER tune.
Sure, except why do you keep saying 91 when you're using 93 octane gas? Bill can optimize a tune for 93 octane, and it's more than just adjusting timing. It includes changes to the A/F maps too. Possibly, some other things as well.
