Did any of this fix your issue? update? Also did you use MAF cleaner to clean the MAF or something else?

 

Cleaned the maf (with maf cleaner from the CRC brand) then changed the plugs and did a boost leak test. Turns out my LICP wasn't on super well (it's the vertical flow from full race, so it's a bit tough to see it and make sure it's on the turbo). All seems to be well with the world now - just need to finish breaking the clutch in.
