Element Hydramist universal instal

[Mazda Carnage]

I purchased a used Element Hydramist kit under some false pretenses, sold as everything included just needs tank, works independently...

The kits is missing the Tank hookup, the jets/sprayers and Y fitting for the jets.
I made a tank and a fitting, still have to source the jets and a 4mmY fitting for the jets.

I have read and downloaded all kinds of info on the Hydramist and Aquamist with DDS3 v8 junction board but still have questions:

Can I run the Element Hydramist off a SDS (simple digital system) EIC (Electronic injector controller), it uses a map sensor and rpm signals to engage two extra injectors (Low impedance) at a set boost, it's controller has threshold (at what boost it comes on) and gain (sets the amount of fuel injected). Does the impedance of the injector signal used matter as a trigger?
I realize tuning will require more work, changing the injector gain would effect the entire hydrasmist set-up and would involve lowering the injector gain and increasing the hydramist trip adjust until the right combination is found.

About the Fail safe for manual boost controller set-up, I am using a Tial external waste gate, all waste gates function the same but the tial uses a different boost controller set up, the waste gate hoses go like this:

. . . . . . . . . . . . ______(MBC)___|(T)_____Top fitting on waste gate
Turbo__________|(T)____________________W aste gate actuator

The MBC is a straight through valve it bleeds off the extra boost desired and sends it to a fitting on the top of the waste gate to help balance the exhaust pressure pushing on the waste gate valve and maintain increased boost.

I planed on install a second bleed style boost controller, use the first one to set default (fail safe) boost and the second one to increase boost while the water/meth injection is on.
Using the standard control valve Mac/Clippard valve in the instructions

I have searched for and wonder if you know off a straight through pneumatic control valve, 12V opened --- 0V shut or are they reversible ?
