MBC's can be usefull especially when you like to change boost levels based on fuel used or type of racing you are doing. For drag racing running 26 PSI on race gas is fine, but for road racing I favor lowering the boost to 21-22 PSI to give a bit of cushion and reduce stress. For the Street I'm finding 23-24 PSI is great. The Dejon Dual boost controller works great for this, just a matter of balancing the WG arm adjustment and the signal reaching the boost controller to get steady boost that is adjustable.

 

I just threw that code today... I probably overboosted and tweaked it... I got the AP and just used the stage I tune... I will contact COBB
