Remember we are at 5000 ft. At this altitude Chad's gage is not very far
off. 14psi of boost would be right at 1.80bar (12.5 atmos. press @
5000ft + 14psi boost)/14.7psi/bar = 1.80 bar. It was a also a hot day on
Sat. (86-87 degf) so this would reduce the 12.5 atmospheric pressure a
little.

I think Graydon is in Mich. which is essentially at sea level so 14 psi
of boost would be 1.95bar (14.7 + 14)/14.7=1.95
