Car could also be in limp mode. when ever mine goes in i only boost 5 PSI. might want to get a vag becuase even though there isnt a check engine light it could still go into limp mode. Could be running lean also due to a boost leak or bad maf

FYI

anything less that 0 psi is never referred to as negative psi. the english/standard measurement for vacuum is inch- Hg (mercury)

my APR stgII and mods hits 1.45 bar peak and 1.1, 1.2 bar sustained ( 16, 17psi)

I boosted at 2psi... blown turbo...

Take a long screwdriver to your wastegate actuator... see if it wiggles around, it shouldnt, it should remain solid and hard to move.... if it flops...it is blown...

replace the hose from your throttle body to the diverter valve, and also, make sure you put the DV on correctly and it is not leaking
