would it matter? lessening the throttle OR climbing up a mountain-- 
same effect.. less of a fual need due to a lesser air charge, right?

I can tell you that in the code for my 7727 turbo app, the baro is 
checked once and only once. now that of coarse could be because the 
turbo isn't exactly at 1 atmosphere at WOT.. so my application 
suffers with the absense of that re-check? I feel robbed! 

I too am curious about the MAP "bubble" pocket.. someone take one 
apart and check it out! seems if there were a pocket, wouldnt it be 
pretty expensive to have such a room or whatever instruments to make 
the reference pocket exact? I skipped a couple of posts forgive if 
the subject is over.
