Nice!!
My guesstimate of boost on stock displacement, stock or RE cam, stock exhaust including cats, 20-21 psi 1900-1950 aircharge.
Yes, most likely your 2 Bar map sensors are maxed out around 18-19 or less. (2 bar is 14.7x=29.4 - 14.7 = 14.7 psi, that’s why RE 2.7 blowers where equipped with three bar sensors which read to about 30 psi of boost or so.
