I'll come back to this...

That sounds reasonable.  I've heard a lot of good ol' boy dyno operators
swear up and down that you need to do three back-to-back pulls to "put
some heat in them thar fore-bangers" to get maximum power readings.  Do
you really think that the computer changes that many parameters on one WOT
pull, or is it just getting the cumbustion chamber up to temp?

Anyway, my Roller sits firmly at 19*, and I run 89 octane Midwestern
All-Season fuel.  Never ever heard a single knock, but I'd like to put it
on a dyno to see if it's really making as much power as I could with 91o.
