what is "This" altitude? and what jetting are you running, because fuel to oil ratio @ 32:1 sounds good, but depending on what "Main Jet" you are running the "Air to Fuel" ratio might be a little off based on your "High" elevation.

He is a mile high, Nick, thinner air, smaller jet??, may need to retard your timing a hair also.

dang EPR, nice call, what do you think degree wise for the timing? -10 ?

Like a rocket key in backwards? oh yes I just did mention installing it backwards, and no that was not a typo!

Just a silly "Guess" heheh. Air weighs lots, and gets THIN when you get up there too high, just move down here to California! the jetting will magically be better!

I run 40:1 here in Colorado. What part are you in? Im betting its just you mixture screw that needs adjusted Try resetting it 2 3/4 To 2 7/8 turns out. May need to clean your fuel system too.

StrayDawg, he can help you foresure. On cars with a distributor when high up they would back it off a couple degrees.

Yup, EFI and spark systems do it to this day, and what about the turbo's on the diesel's EPR, they have something called an anoriod (spelling) to adjust the boost / compression and obviously the fuel timing.

Variable Vane Geometry (VVG) turbos are COOL! :cool:

I know a couple "Things" about engines too. :eek:
