Good morning ,

having trouble keeping up boost.

car is sierra 92 , 4x4 , MSD stage 2 chip closed loop , RS500 cooler , greens , T3 , scorpion exhaust no cat , cone pipercross filter.

- checked the system out with my air compresser to 2 bar no leaks.
- tried to wind the actuator further no luck either ( is a brand new -31 one )
- fuel pressure is spot on 3 bar on idle
- car goes overboost 1,5 bar , stable to 1,2 bar . I should get 1,7 bar stable 1,5 bar.

Only thing I donnot know what is the difference in 2 bar and 3 bar MAP does anyone have the serial numbers for these ? I assume I got a 3 bar
MAP sensor.
