MAP Pressure

[Cummins Tn]

Just curious about a few of the numbers out there in the 6. 7 trucks. My insight shows a MAP pressure of 42. 6 in (almost) full throttle conditions. Is this number in psi ? I am the only person in the area running a 6. 7 with a insight. Post em if you got em.

Map is atmoshere plus boost

So the atmospheric pressure of this area at 70 degrees is about 14. 65 psi. With a MAP sensor reading of 42. 6 my boost would be 27. 5 psi. That is very close to what I was reading. Cool!
