Gentlemen,

I was driving along when all of a sudden the boost was all over the
place 1.6 -2.1-1.3-1.7 and then 1.0 steady.
The boost comes not seem to come on anymore. It will not go over 1.0 but
sounds like the turbo is trying to spool up.
I am running a k26 turbo. Any ideas? I have not had the chance to take
off the motor shroud to check the intercooler crossover hose.

Thanks

Andreas
