are you sure the boost controller is set up correctly and not backwards, also check for boost leak tests you'd be surprised at what you may find. Also is this on the t25?

What brand and type of mbc? Describe how you have it hooked up, pics would be nice. It could be the mbc as captd108 can tell you first hand.

Take it back off until you can divine from one of the 500 threads on here about MBCs the proper way to hook it up.
