co2 boost control

[TurboDetroit]

those of you using fast xfi to control boost through an external wastegate/co2 setup. how many boost solenoids and what kind are you using. are you using 3 port or 4 port and how did you set that up?

I would say most are using the 3 port solenoid that can be bought at Grainger
