Anyway - with the boost turned up, the smoke appears to be gone at high RPM. The EGT's still get higher than I'd like but now I can hit over 90mph before EGT's make me lift. I think even a small IC might help out with that. AP-22 indicated power is up at least 20hp from previously with the stock turbo, so it might be 165-170hp at the wheels now. Launching with moderate power braking (to get the boost needle off zero) results in spinning both 225/45/17 tires (!!) if the pavement is not clean & dry. But, I was able to get a couple of test runs:
Summary of acceleration times:
0-60 = 10.7 sec, 0-80 = 19.5 sec, 0-90 = 26.0 sec (stock IP)
0-60 = 9.3 sec, 0-80 = 16.3 sec, 0-90 = 21.9 sec (maxed-out stock IP)
0-60 = 8.6 sec, 0-80 = 14.9 sec, 0-90 = N/A (hybrid IP, stock KKK turbo @ 20psi)
0-60 = 7.7 sec, 0-80 = 13.4 sec, 0-90 = 17.1 sec (hybrid IP, 350SDL Garrett turbo @ 22psi)
Due to high EGT's, I could not test to 90mph with the stock turbo. I also forgot to test 1/4 mile data with the stock turbo, but with stock IP (maxed out) it was usually around 17.0 @ 80mph, today with the hybrid setup I got 15.9 @ 86mph, which ain't too shabby.
Coming soon: Dyno data and videos of the gauges at WOT. I'd like to test to 100mph (for comparison to stock) but I need to get EGT's down a bit more.

I got the Hallman boost controller installed today. I pre-set it on the workbench and it was pretty close, about 20psi peak, dropping to about 18psi. Another turn of the knob got it to about 22psi peak, dropping to maybe 20psi. I haven't been able to watch it real closely under power though. I need to take a good video during a WOT run to capture the data. The good news is, the 3.5L turbo works waaaay better than the littler KKK.
