Ran a few logs and I saw 12 psi under part throttle a couple times, so I pulled over and loosened the arm a half turn. Boost dropped back down under part throttle, and now Im seeing a peak of 13.6psi. Seems like the car is a bit more responsive down low now too. For any WRX owners that either arent seeing target boost or are getting some wastegate flutter, I highly recommend it.
