Thanks. And yes, the tunes are leaning the fuel curve out a bit at high RPM. In the low end and midrange, they are probably enriching things a bit since it doesn't seem to result in any power loss and presumably provides a bit more knock suppression/timing stability. At least that is what I'm doing
