I have a received a couple questions regarding my proposed control system via PM that I will try and address for everyone.
It is common understanding that an exhaust brake works by providing drive or back pressure for the engine to work against, slowing the engine down.
With the veins closed down all the way, there should be around 60psi (hopefully) of drive pressure produced, effectively acting as an exhaust brake.
For my proposed control system, It will require a small amount of drive pressure to expand the pneumatic cyl a bit to hold it at a minimum position to provide adequate spool-up and not choke the engine down killing the throttle response.
A byproduct of closing the veins down to produce the drive pressure, is that the turbine will now be spinning like crazy! Hopefully I can produce a lb or 2 of boost at idle to combat the dead throttle (if any) that is produced from the closed veins.

I now welcome constructive criticism:hehe:
