Incidentally, I must be fey. Just a few days after this thread´s discussion of intercooler leaks, my Allisport upgrade fatigued around a mounting bolt - quite a major leak. Why does it have to happen when I most need it? We are at 3000-4500m altitude!
Anyway, it just hissed a whole lot when the turbo was "on", and she was pretty sluggish. In the next town, we had it welded up - hope it´s better than Allisport´s welding!  .
Back to "full" power now, though I am half-considering raising the boost a bit while we are at altitude.
I was a bit worried that it might suck (unfiltered) air through the hole when idling, but I tested with some soapy water, and it always appears to have some positive presure.
Btw, in the mountains a turbo diesel really shines - it´s much easier to compensate for the rare atmosphere.
