Low boost on twin turbo?
It just won't make boost with the controller

If you have it plumbed as described, and solenoid/controller tested as described, then it will make more boost when you increase the setpoint duty.
It may take 15-20% in some cases before there is a change, but it will increase boost.
Try it set at 50 and see what happens, just being careful it doesnt go too high. You could set the overboost protection to say 15psi or so

Settings sound sensible.
Try resetting the unit, but physically with the test mentioned, you have proven it works.
Are you able to see the poppet valve in the wastegates when installed ?
ie could you reconnect everything, hook up a pressure source to the EBoost and the compressor side of the solenoid to do a live test and visual inspection to see if the gates open/close as expected ?

Configure as per Single Port, Single solenoid twin turbo on page 9 of the instructions.
This is the simplest and easiest configuration.
At 0% duty or controller off, you should be able to blow right through and operate the poppet valve in the w/g
At 100% duty you should not be able to blow through at all and valves should remain ****.

And still no increase ? Even at say 80-100% setpoint duty ?
The physical installations sounds correct. You've tested the controller and proved it is functional by blowing through the solenoid when it is being pulsed.
Really...it cant do anything but work ? You've just tested and proven all parts work.
Sure there isnt some of the hoses blocked ?

Really without seeing it and doing some testing....no idea where you need to go.
Everything you've tested sounds good if tested correctly. It should be working.
If you can get a multimeter or scope and hook it to the solenoid wires.
Then read either duty cycle, pulse width, frequency...any of these whilst driving and boosting with different SP1 values.
This will confirm the controller is sending a signal to the solenoid during actual real live use.
On a voltage setting might give you a reading, just not sure if it will be a usable one though.

I think I'm just gonna call it a 500 loss and order something else. I've never had so much trouble with a controller in my life. I had a msbc-1 that worked flawless on my other turbo car, I just figured it would be nice to have a boost gauge built in

Doesnt matter what controller...they all fire a solenoid in the same way.
It really should be working.
If you can test as above and prove the solenoid is getting a sensible signal, then something with your plumbing is not correct.
But the previous pressure tests should have already proven this when the ports switched on the solenoid.

No I didn't do the the other test as I was fed up with it. I unplugged the 2 hoses going into the solenoid and plugged them into the manual controller. Turned the manual all the way down and I had 8psi which is what springs I have in my Tial 44mm wastegates. 2.5 turns gave me 10psi, 4 turns have me 14.5 and 5 turns gave me 16psi

If you still wish to use the Eboost...although all previous tests did appear to show a working unit
The latter test I mentioned should at least tell you whether the problem is the controller or the solenoid
Although all the earlier tests if done correctly did appear to prove all was working...even if that didnt translate into a working system
It's all a bit weird.
