Did you look for exhaust leaks or gasket leaks?

Well you maybe getting some knock . You need a logger to confirm. Is your car awd or fwd? I would say preform a boost leak test as well.

yeah, i agree. you must be getting a lot of knock at 15 psi.

getting a better flowing intake filter and pipe will help the turbo "breathe" a little better and spool up faster, that might help with your time.
