So after ordering the greddy b-spec II as my EBC...I started looking into whether or not I needed/wanted a boost gauge as well (so that it's easier to see the taper and progression in boost). Since the stock boost gauge is set in kgf/cm2, I thought it might be helpful to get the conversions made for PSI which is the more common pressure measurement it seems. I rounded using the hundredth's and only included the 1.6 for those that may have flashed the car and see the spike above the 1.5 (which would logically be the 1.6 mark or higher).

Hope this helps the other new EVO owners!

15 psi = 1.1 kgf/cm2
16 psi = 1.1 kgf/cm2
17 psi = 1.2 kgf/cm2
18 psi = 1.3 kgf/cm2
19 psi = 1.3 kgf/cm2
20 psi = 1.4 kgf/cm2
21 psi = 1.5 kgf/cm2
22 psi = 1.6 kgf/cm2
23 psi = 1.6 kgf/cm2

 

The beauty of the metric equilivent to PSI is that 1 Kilogram of force/centimeter squared is equals almost exactly standard atmospheric pressure at sea level of 14.7 pounds/square inch.
