Alex, from what I read, you don't have any problems...

<<     I have no boost according to my gauge, just vacuum.  This is with the car in the air and no pressure on the engine, that may be the problem,yes/no?  I have removed the intake pipes and checked them plus the turbo
impeller.  All seem perfect and impeller spins freely like it always has.  I clamped off the control line for the bypass valve and that changed nothing.
I don't hear any whistling or gushing air plus the engine runs fine at idle
and when revving.  If there was a huge vacuum leak I'd get no boost in the manifold but I'd expect to hear that too.  Tips?>>

You are not going to make any boost without any load on the engine, you need to get it rolling, to get boost at no load takes some serious revving and punishment, take the friggin car for a drive already!!

    <<Oil pressure levels out at 1bar on the gauge when the engine is warmed
up.  Upon start up it goes to 5bar and holds, then drops to 2bar and holds,
then when the engine is getting completely warmed up it drops to 1bar and holds.  Is that too low for idling safely, no lifter noise and no scary
noises?  10W-30 dino oil by the way, no oil smoke from the tailpipe and compression is 170-185psi on all four cylinders.>>

Your oil pressure is fine, it will lower at idle with the turbo and oil cooler, but its fine, mine is the same way..

    <<Smelly black smoke from the turbo/EM area when engine is running and hot.  I think it may just be burning off junk from whatever the EM was
treated with, black powder coating almost, turbo has that rebuilt gray paint on it too.  It looks like the smoke is coming from there, no smoke from the
tailpipe or odd smells, so must be an external thing.  Anyone?>>

Yes, like I said, you need to take it for a drive and really heat things up, once that turbo is glowing red there will be nothing left to burn off...all that brand new stuff you put in there is letting off some serious vapors, take if for a drive...

Have fun!
