I already have two MAF's and they react the same (mentioned before as possible problem for my earlier and ongoing powerissues, that why I bought a second one when I found one for cheap).
After driving around for a while, the smoking is less and can only be induced by powerful acceleration, so I am slightly less worried then when I started this thread
We'll see what the online seller says about the condensor.
And I will continue my quest for power under 1800rpm...
I checked some online DIY projects to put overpressure on the inletsystem for finding leaks to see if I could make them cheap. They are sometimes less than 10$, which includes a rubber part that is 25$ in the Netherlands
I think I can use an old inner tube with valve I should have lying around and just clamp that around the turbo-inlet.
