Power limit on charger

[Andy]

Tristan's car is running a smaller pulley than yours, so that's another few psi difference. I'd not worry too much - you might not have the boost gauge plumbed in to the same point as him, and I'm guessing that the boost gauges you're both using are not fully calibrated instrumentation grade bits of kit so some variance there is to be expected.

only used a gauge when rebuild was done to see that rebuild was ok,  my gauge red about 0.65 bar ~10PSI at 5500rpm
Was pretty funny driving with a tube from hood trough passenger window. not an ideal setup probably
