So it turns out, I was mistaken, one of the valves is for the PCV system, but my 8.1 has an internal pcv system and isn't acceible. TireRod told me to tap vaccum and put a one way check valve on the the tapped. So can I use this regulator, e-valve, thing on another wastegates?

OK, I have decided to go with two small wastegates. If I do do this, what springs should I use? I'm not sure how to figure it up with two wastegates. i am going to take mine apert in a minute and see what spring it has.

i like to go a little lower on the spring than the minimum boost i want. lets say your lowest boost setting is going to be 8psi. i would get the 6psi springs. with a 6psi spring you could see anywhere from 5psi to maybe 8psi. then use a controler to get it right where you want it.
then figure whatever you see for boost on spring only you should be able to go 2-3 times that amount with a boost controler before you have to get a higher spring.

So say I want to have a low of around 4-5 psi and a high of 8-9 psi, I should get like two springs somewhere between 2-4(if they are made that low), and then use the controller to get my 8-9ish lbs??
And the box the gate came in says " .4 bar "

i think the lowest they go is .3bar. that should be right in that range of 4-5psi but depending on the set up could be a little higher than that. you wont have any problem geting 9psi out of it when you want as long as the turbo is large enough.

So can I do this: Leave the .4 in the gate I have and get my new gate with the .3 or whatever the lowest is. You know, mismatch them, or will that really f*ck things up?

i dont think you will get the low boost you are looking for if you dont put low springs in both of them. i see above i posted up about a .25bar spring. i would get a set of those. with the size of that engine you will need to by pass as much exhaust as you can to keep the boost down.
