My Home Made Dual Boost Controller 

 

The reason why I made this MBC is because I'm tired to look at my boost gage to see if I'm creeping over 20PSI of boost .

The Dual boost controller that I have in the car is a Turbo XS kind and that one is nothing but a stemming pile of $#!^.

One of the two inputs ( the bottom barb fittings ) will be controlled by a switch able solenoid that will allow air to pass throe or not with a flick of a switch . It should be the low boost setting , because that's the first one that will get activated when a set boost is reached . In other words , It will be blocked if you desire the high boost setting . If you want the low boost , that solenoid needs to be open .
