Damn noobs.

Psi doesn't matter. It is the CFM that the turbo flows. Different turbos make different power at a given psi level, so trying to pinpoint a particular psi level the engine can take is worthless.

Also, tuning has a huge effect on how much boost can be run. A half assed fuel management system of an FMU and missing link will kill any motor at any psi, whereas, a strong fuel management setup of Hondata, Crome, EMS, etc will allow more boost to be run with safer results.
