Using an Actron Scanner to measure boost???
I recently purcashed an Actron Scanner Plus to diagnose codes on my other cars and watch the IAT temps etc on the Benz. How accurate should these things be when reading the MAP KPA readings?? You think they're pretty reliable readings?
The reason I ask, I saw 200+ MAP KPA readings on the scanner after some test runs- that's 29psi of boost. As far as I know the M275 AMG was limited to 22psi?

I believe you have to subtract atmospheric pressure from what ever its reading. That depends on what elevation you are at. I think the M275 amg is limited to 19psi stock, but I don't remember for sure.
