I went for a quick shakedown run before the snow flies again. I did not have time to set up a proper camera rig or computer to log data. This super shaky video is from my phone sucker-cupped to the window.
Based on butt dyno and Mk 1 Eyeball data logging, all I can say is OMFG. EGTs are 200°F down across the board. No more smoke on my performance tune when rolling into it. A sudden mashing of the pedal still gets me smoke. Response is instantaneous. Boost starts building on mechanical boost gauge at about 1,650rpm.Steady state cruising at part throttle, 50mph, about 1,800rpm gets me boost around 2-3 psi. Working on the video describing everything I experienced on the short drive. In the meantime, here's a teaser:
Methinks I have to turn the boost down a little.

Now to answer Sous' quesions.
I haven't hooked up the tach signal yet. It is only used for exh brake cutout at set rpm and not used in the vane actuator position alogrithm for building boost according to DPS. I still plan to ask for clarification on this.
The power cycle is only needed when changing the setting for the vane starting position. Theoretically, once this is set it should be left alone. Practically, I can't help but keep tweaking.

Item number 5 is concerning though it seems you have a bit of a work around for it. Are you saying that in order for the vanes to change their actuation level (exhaust brake to wide open for example) there needs to be a power cycle to the controller? Perhaps there is a check box or setting in the software somewhere you have overlooked. I sent you a text about this with some thoughts.

I heard a boot blow off I think... What is your boost gauge max, 40 PSI? (EDIT: I see in the still image of the video the measurements stop at 35, but the peg seems to be at 40 or so)
Watching that video reminds me of riding a C-130...
Well done Leonard, now for some fine tuning and then enjoying your time and work invested.

The cold side CAC tube to y-pipe boot. I didn't realize the CSD kit does not come with a replacement for that so I reused the factory boot. RiffRaff boot and clamps already inbound.

It is hard to see and I know because of the boot blow off the reading is not a good representation, but it looked like the EGT gauge hit a wall at ~1000*.
Just to recap and for anyone following along on a mobile device, Leonard is running a Borg Warner 366 with a Turbonator turbine and 205/80 injectors.
Time to update your signature good sir!

You fellas have a lot better eyes than I do! 
At least I have you guys to point me in the right direction from time to time.
Jason, he hit almost 1600* (I think) with the GTP38R, but he had a boost leak as well. Maybe he can chime in with what a non-leaking GTP38R rigorous run would hit on the EGT gauge.

Is there a FordTruckNSFW version of the verbal commentary sound track after the "pop"?
Or was it just stunned silence?
Visualizing myself in that situation... it would definitely be NSFW... until I got the hood open to confirm what happened.

Oh FTNSFW was in full effect. That recording will stay in my private collection.
Here's the full shakedown video.
I have already got footage with a better camera from Shakedown 2.

Test response to FTNSFW to confirm forum software issue reported by FTNewsignature.
If you see a signature of mine below this post (which would be a rare sight indeed, as I don't do cigs, but wanted to test a problem report), then FordTruckNothing wrong on FTE's end.
If not, then, FordTruckNoticed a problem with our software that needs a fixin.
