Was able to sneak some testing in last night as the pavement dried out enough in some patches to be able to do 4th gear pulls. But Old Man Winter is making testing difficult. High today is -8F ...
So I have a configuration now that seems to be very promising. The analog gauge shows (sorry, no video's yet) boost staying below 30 psi everywhere, and the ~2800rpm spike is completely gone. And I kinda like the sound when the wastegate dumps to atmosphere ... Yes, I'm a bit Redneck.
Boost log comparison of 4th gear pulls with and without the external wastegate. Data from before the external wastegate is from this thread:

Note: The Android Torque app reads ~ 4 psi lower than the analog gauge at peak boost levels.
