How much Vac

[fratzke7]

not sure about vacuum, but with that cam and pulley you shouldnt see much over 12 psi or so for boost. you dont want to run much more than 13 seeing as how our MAP sensors only read up to 14.7 psi (2 bar).

Ok so where can I get a new map sensor that reads higher!?

You could get a MAP sensor that could read higher, but you would have to modify the computer to be able to interpret that reading, and I don't currently know of any way to do that.
