my POS paper tial gasket is leaking(manifold to wastegate) can it cause this problem

boost pull hard in 1st and 2nd but bog sometime. 3rd gear, 4th gear and 5th i can feel and hear the turbo spool up but car does not pull. feel like i'm towling a semi . my boost meter show i'm at full boost(6psi) but car stop pull after turbo spool up

 

any kind of leak can cause problems . just take the gascket off, make sure surface is clean and run with no gascket. thats what alot of people do. never have problems

If you showing full boost than that is not the problem.. The only way it could be that is if the leak is bad enough that the boost drops. Why is your gasket leaking? are the surfaces flat? try some orange rtv

 

if not the gasket , what do you guys think can cause that problem
