The VF39 CAN'T make more boost than is good for the engine in the lower gears (1-4th), 5th and 6th it appears that the midrange boost can get up there, but I have no evidence for or against the safety of running 20+ PSI on a stock turbo, tune, and fuel system STi.
You will compromise turbo life running higher boost pressures on the VF39.
