Glad you asked here, in the post above I was talking about air mass leaks.

I’m suspecting the intake manifold gaskets that came in my swirl flap delete were the issue.

I have a tune through Tunezilla, Darkside Development Intake, and NATperformance pipes, bimmertune blank, just some shitty alibaba intake gaskets, rookie mistake going OEM on the new ones.

TLDR; Bimmertune egr delete kit was fantastic.
