Hi all, new to the forum and new owner of a Mazda 6

I bought mine knowing it was smoking (burning oil) i was told this was the turbo seals leaking.
This weekend i had swapped out the turbo with one i bought second hand but after installing it, it doesn't want to boost over 3k rpm.

It still has a lumpy idle but revs upto 3k fine but it doesnt rev much further than that.

I'm wondering if perhaps I didnt re-install the vacuum pipes correctly or perhaps maybe the wastegate actuator on the bigger turbo isnt working

Would anyone have any ideas where the first place to look is?
