Jake, i gotcha now bud.
Rich, I understand density tables and do not disagree with you...but is my statement incorrect in saying if we are going for a certain % at sea level..that it should not do as well @ 9k? I know at least in dmax world i had no issue running the same table from here to there... I'm completely understand that this may not work in others applications as each truck is different...
I could see the event of a guy running very conservative timing wanting to step it up as alt changes...but generally everyone is going for the most efficient "higher timing" setup...
