When increasing boost pressure, you always need to keep an eye out for possible problems. In my case, about 1,000 miles after increasing boost to 14psi, I had two weak turbo hoses blow out. After 160,000 miles, they had become soft on the underside, the added pressure caused them to fail. The short hose from the intercooler to the pipe going to the intake manifold.

As you can see, this was not very
obvious. The split closed up when
the car was not under boost.

Until the pressure got high enough.
Then a hidden flap opened up.
This caused the car to run very rich
only under boost.

This split was on the bottom side of the hose.
