Manual Boost Controller
M&M Racing Manual Boost Controllers: This is just another pressure relief style boost controller. For the DSM crowd it accomplishs the same thing as the $100 Extreme controller and also the Marc Hallman controller. For the turbo Dodge boys you will probably recognize this as a Gus Mahon type "Grainger valve" . This is just a lower priced alternative to spending a fortune on an electronic controller or on another manufacture's more expensive manual controller. Does not include any vacuum line.
