2 bar map is good for 14psi, the 3 bar is good for 28. I am running 9 psi on a speed density tune with a 2 bar map.

Unless you are going to run over 14.7psi, 2 -bar is all you need.
Im also using a 2-bar on my single turbo setup @12psi

A 1-bar (factory map sensor) can only read 0 vacuum and no boost. It can only read atmospheric pressure.

Good Luck!
