Translation:

The only code I'm getting is Code 52, as the TSRM states it's for the knock sensor circuit. If you drive normal in first gear, then in second, or try to boost in any gear, it will cut out and sounds like a woosh of air, and I'm not building any boost. Even if I romp on it in every gear, I get no boost, no pull. It feels stock. The knock sensors are new.

haha shaeff!

Sounds to me like it's a boost leak. I've held off chiming in here, but it seems like it runs like a car with a bad or unplugged AFM.

Have you checked the IC pipes? Make sure the pipes didn't have any cracks in them. (I know mine were rock solid and didn't resemble rubber any longer)

I don't know what to do if someone isn't willing to help their own cause!
