You need a hobbs switch, and mac valve if you are on piggypack and just the mac valve if you standalone.
Not saying that it wont work with a stock ecu but majority of the people that made great power band with it were on on Ems..

You don't need all that there are lots of ways to do it, that MAC valve is basically a boost control valve, same as used by the aem. U need a controller like the EMS or the hobbs switch thing To drive that specific valve. a manual controller may work, but if you have a standalone the MAC valves are better because you can tune it to open up under diff parameters in the aem instead of 1 static setting, like gear, speed, rpm, etc, basically all the ways you can control boost with a standalone. Those valves can be had on eBay very cheap. They are standard industrial air valves.

Thanks Ali. I did some digging, and it seems that they recommend the hobbs/switching valve setup because it can open the gate much faster and more fully than a straight mbc signal.
I found a thread on SF where a guy used a mbc, and it worked, but the modulation was slow, and the valve had to start opening early in order to be fully open by the desired set point. This lowered the efficiency of the valve, and though it did work to a point, the hobbs setup worked better for him.
I guess that answers my question though. You CAN use an MBC, but you wont realize the full potential of the valve.

That's what I was thinking all along.
Hobbs switches are ancient anyways.
I'm sure that if you used a turnbuckle setup on the QSV flapper arm, you could get that extra modulation to open or close the valve more.
Besides, I've never seen an electronic valve get the turbo spooling as quick as a good MBC. Most of them hold shut until the desired pressure is met, then it bleeds off.
Like the good turbo XS valve with the coarse and fine adjustments.
This QSV business is getting interesting.
