This is good to know. I will first address my fuel delivery, head to lower elevation with as much margin as possible, then do the pulley. I really do think I have the margin in the MAF tables for it, but the calc.vet probably won't happen before I leave hence me waiting to pulley down. I will then post up with logs and before/after tunes so my blending can be judged, I really suck at that and want to get better.
