Default GT35r problem/ boost problem

I have been having this problem for awhile, Car would not build boost when hooked up straight to the WGA, but when I threw a MBC in the line, it builds boost, but slowly. What could be the problem, when I have the intake off the car the turbo is spinning, but when I drive it, I dont hear it spool. main mods are fully built motor, ported & polished heads, bigger valves, TGV delete, perrin gt35r kit.

Have you checked for intercooler/bov leaks? Since you're running a blow through setup, any leaks pre-maf won't affect the AFR
