Turbosmart tee boost controller

[TurboTime]

Gt 2860 with a 6-7lb internal wastegate actuator. What max lb boost increase can I expect with a turbosmart tee?
Thanks,
KI

I put on a hallman pro (similar tee type, like a pressure regulator) and cranked all the way in I got up to 25 lbs with my 2860 with a wastegate that would maintain 7 psi unrestricted.
Not sure if it would get more because I ran out of fuel flow capability at that time...
