This is a question that haunts me daily. I'm on 16psi on a mild tune on 91 which is what the tuner felt was safe but I'm always haunted by the thought that it may be too much.

Cant think of anyone off the top of my head. I know there was talk amongst the guys about running that kind of pressure with the new GTX30 and getting about 650 out of it.
