Sorry to dig up a dead thread, but I have just noticed that my R32 gtr std boost gauge goes over the +7 std reading when boosting.
It has a cat-back (soon to be full system), and I can't feel the boost restrictor around the yellow dotted line (removed?)...
My question is, is this safe turbo wise, and, what equivalent PSI or bar should I expect? I will try and hook into a boost gauge this weekend...
