Just a simple cleaning of the butterfly valve with brake cleaner and a cloth should fix that. However that may only be a fraction of your problem. Now that mike has pointed out the fuel issue it may be due to the tune. However the best thing you can do now is clean the TB, clean the MAF and do more logs and see what you get. If its still lean after clearing the codes, and resetting the fuel trims after a few drive cycles then you can hit up unitronics (or whoever your tune is from) and show them your findings. Im curious now what the result is gonna be from this.

 

I think the issue is that my turbo outlet hose is kinked - I wil need a 45 degree coupler and ill make a custom aluminum outlet pipe- I will post pics of the kink
