Along with less timing corrections.

I still have concerns about my boost but with the MAF off I was closer to where it should be. I still think I need a new boost solenoid. I did also install the turbo inlet gasket last night.

Any updates? Also what codes were you getting exactly?
Im getting these following codes-
2BCB
2D2F (Shadow)
And 2D34 after replacing upstream o2 sensor.

N55 with FBO, mhd stage 0 tune.
