I did my first 115 log & have an excel sheet. Ho do I convert the mbar
into psi for requested & actual boost level? I know how to make graphs in Excel but not sure of the conversion & which data is the most important to look at. Anyone? TIA

Yup - SLC. I don't know if that is the correct way to convert these readouts
by just multiplying the mbar by 14.5 since the readouts show 850 at idle and up to 1680 at WOT. I'm not sure.....

Were you at Shaggy's Velvet Room Friday night?
Excellent Citizen Cope/Marc Broussard show! That's a great venue-- small, with a large bar! 
We were in Park City for the last week. What a break from this Florida weather...

yeah i read bar, not mbar...
so the conversion is 0.0145 not 14.5. sorry bout that. see if that looks more realistic.
slc also. keep in touch with all this info, i am interested to hear how it goes and what you find out.

That is better. I'm hitting 1680 peak mbar but according to the other posts
you subtract 1000 for ambient air pressure at sea level. I was at approx. 4,800 ft so the amount would be lower. At idle it is about 840 mbar.
1680 peak - 840 ambient = 840 x .0145 = 12.18 psi or .8398 bar
We'll have to get together to match up data. I'm probably going to be chipping soon. My concern was I was hitting 12+ psi according to my boost gauge and sometimes 14 when it is 90+ degrees. Apparently a stock chip can go higher to compensate for high temps & high altitudes.
