I did some googling and it appears a stock GTR runs ~12psi... so it seems reasonable to me... though not exactly what I would have expected.

The million dollar question here is - can you change the springs on the OEM actuators, or adjust the tensioning?


Unfortunately not. I did research exactly that and everybody including my turbo said that running on just wastegate pressure (0 duty cycle in his gtr) it ran at about 8-9 psi. It's really weird that it's 12 psi on my car.
