I didn't feel much of a power difference from the timing spacer. But it did seem like it made the upper RPM range more usable. Seems to smoothly sail up from 2500 to 3000 now.
Ran it with just the spacer for a few days, then added the pin. The pin definitely added more power at full boost, I can feel it for sure, and I see 2lbs more max boost without adjusting the boost controller, and higher egts. All that said, I'm sure it would have been more of an eyeopener if I hadn't already rotated the stock pin.
