vex will become famous soon enough
So I ended up melting my MAP line... oops. I replaced and plumbed it into a port away from the turbo and took a chisel and bent/capped off the port by the engine. I figure the penlum after the throttle body will see the same vacuum numbers that the original port did, or at least be some what close.

I do not think the bent/capped off port sealed correctly as I'm only getting around 14-15inHg at idle, though I know the car is capable of pulling close to 19inHg at idle. which leads me to believe that there might be a few little vacuum leaks that I can find and fix to eliminate them. The problem is I don't think anyone makes silicon vac caps and all the rubber ones I put on seem to dry out after awhile.

Though since I did relocate the MAP sensor to the new port my smoking problem seems to have vanished for the most part. I still think I may be running richer than I am being told by the AFR but I think that could be because of an exhaust leak from the EBAY special V-Band and the ATP V-Band adapter for the turbo.

Still burning oil, but the large quantities of smoke do not occur. They are however prominent portions of light smoke with a bluish tint that could easily be from the oil injectors or excess oil in the combustion chamber... though nothing to really consider extreme in nature.
