Cats working? How to tell? WAS: No power on hills - helpdesperately needed

[Ingo Rautenberg]

Oh so true.  A certain Urq owner, after having recently replaced his K26
with gnawed-off compressor wheel, found that even with replacement turbo
boost (even with modified box) would not go past 12 PSI.  After a few days
at Steamboat Springs, boost went down to zero.  After replacing with an
even-nicer k26 -- still zero.

What had happened:  Cat had melted and clogged the rest of the exhaust as
well.  After more free-flowing adjustments (including glass-pack), rumors
are that he was drifting quite nicely through the course today and able to
adjust boost to 18 psi and beyond if he wanted to.... ;-)

Ingo -- not at Steamboat this year : (
