High EGT's, low MPG's and 20 PSI of boost, assuming you have stock injectors, makes me wonder about the MAP sensor. Is the smoke level normal?

No, smoke is excessive. Would the MAP sensor cause an odd sound? Seems like maybe and overfueling issue would though.
It's very rythmic so i'm thinking it's concentrated in one cylinder, which is also why I thought it was an injector.
