Ok spent some more time looking at the various Timing maps for The different tunes... The stock tim ing map seems to be a lot more complicated than the ones Bill is using in his tunes... I am guessing there was some software engineer at Ford that had nothing better to do.... My guess is they were running the engine on an Dyno and tuning the Timing and other factors to get the lowest emissions vs power output???

Anyway the one thing that stood out is that a lot of the stock timing curves seem to drop around peak torque and then rise again then taper off at high RPM after peak HP... Is there a reason for the drop around the 1600 RPM range as I am wondering if I need to preserve that in doing the altitude timing?

Also should the Advance come on later the same or earlier with the higher altitude?

Am I asking too many Questions???
