Simply put, I have a 6 port turbo that I’m keeping the aux ports functional. Wastegate spring is 7psi. Although I may go up to 14psi. I can support it in theory. I’m familiar that the aux port actuator open fully at 3psi. Can the aux actuator take the full psi of boost or do I need to regulate it? MAC valve perhaps…

 

if it was mine, i'd be ok with 7psi, but much more than that and i would probably want to limit it somehow.
