I was under the impression that it is richer versus leaner through 7.2K and 9K. Above red dashed line is not richer? Am I reading this backwards? (forgive me -first timer here with reading a dyno run) The tuner did mention that he could make it leaner through this range and get a few more ponnies out of it but would not be as "safe" on the engine like it is showing now. So I assume the answer to your question is yes, he said this is the safe route and okay.
And you are correct, the MS map (map switching) is engaged when within the 6K thru 10.8k rpm range if I'm outta 1st gear, >85% throttle and starter button is pressed. Otherwise i'm on the engine map.
