I need help plumbing 2 stage MBC I need some help with this I've never done it before so if I could get some help and a quik drawing it would go along way.
What I would like to do is run 3 stage manual boost controller , here are the parts I have :
2- 3 way Mac valves
2- manual boost controllers
2- adjustable Hobbs switches
What I would like to do is run 5-7 psi boost off the wastegate for the 1st stage on the street
and with a flip of a toggle I would like to go to the second stage for 15 psi of boost
and another toggle for the third stage of 20 psi
and if I have both toggles armed the hobbs switches will open the Mac valves at there set psi / the 1st hobbs would open at 15 psi and the second at 20psi
Now what I would need to know is how to plum the wastegate / blowoff / were to take the boost from and how to plum the MBC'ers
I am lost here so any help would be greatfull
Thanks mike

I am using ball and spring type controllers .
I have 2 MBC / 2 Mac valves and 2 adjustable hobbs switches to activate the mac valves .
I would like to use the the 1st stage on the street with 5psi and with flip of a toggle for the next 2 stage's to be armed and will open the valves with the hobbs switches and theres 2 mbc somewhere in there.
Can this be done
What psi spring would i use in the wastegate

Run the waste gate spring you want to be the lowest boost setting, you can't run less than the spring (easily).
All you are really doing is running gate pressure for 1 settings, then 2 other settings with 2 different controllers. The valves are just isolating which controller you want to be active. This can all be done with the 2 valves, 2 controllers and 2 toggle switches. No need for Hobbs switches.
Example controller 1 set for 10 psi, controller 2 set for 15 psi
Green arrows show boost flow in the 3 configurations.
If you don't follow, do some quick research on how a boost controller works and I am sure you will understand.

If I run pressure to the top of the gate to make more boost were would I take the pressure form and how would I regulate it and would I need a bleed valve
Were can I buy the parts needed to do this
