Can you run to much OIL pressure,

my brother's mk3 RS Turbo as just let go whilst on it's first run.
The turbo was bought brand new about 3 years ago from Turbo technics and is there stage 3 version, tonight was it's first real ride out as after 5 long years he's finished his rebuild.

Now the Turbo as only done 27 miles, yes 27 and just spat oil all over the bay, he as fitted an up rated oil pump and from cold idle the pressure is about 75psi and on warm idle it's on 20 psi and when rev'd at 2000 rpm cold is 80 psi and warm is 40 psi, is this to much pressure or is there an issue with the turbo, although after 3 years warranty means nowt
