i use map A and use 93 octane. and when i need a boost because i have to play, i add a booster to my gas.
also sometime's map B throws a cell code. it has done this for some in the past.
my truck can run both map's without any issue.
i also tried 89 octane once, just to see if there would be a problem. none found. ran great.
