This morning, before reading this e-mail, I was able to manually move the waste gate with the pushrod still connected. I also shifted the intercooler piping a bit to give more room for the signal line to get to the can (which has always been a bit cramped and looks like it's kinked, but it's always been that way and it's previously always worked). Still no change, unlimited boost.
Tonight I'll see what happens if I bypass the solenoid and go directly from the turbo output to can. Thanks for the ideas!
