I am already thinking the worst.
The stock boost gauge will read no more than 0 or maybe 0.05+. This was after normal full throttle boost in third gear merging onto a freeway. No problems, no odd sounds. The next time I "called" on the turbo a mile or two down the highway, nothing. I reset the ECU using the AP to no avail. The gauge seems to go into the negative numbers normally when coasting or under light acceleration. Give it some gas and nada.
Off of the highway the WRX now sounds different somehow; maybe a bit louder and more guttural. I could not hear any exhaust leaks once parked with the hood up or underneath the car. With the stage 2 mods and the obvious autoxing I’m not expecting any warranty help from Subaru.
