Woah woah woah…be careful with statements like this. Boost controllers can not make a turbo system generate more boost at any specific rpm range if it’s not physically possible. A systems ability to build boost is mechanically limited by a number of different factors including, but not limited to, the size of the motor, volume of air, size of turbo, etc.

So, boost controllers can not help you build boost if it is not physically possible for your motor and turbo configuration to do so. What boost controllers do is help you maximize what is mechanically possible.

Yeah, those comments are generally accurate. Good on them for recognizing your lack of boost control from your trq curve. Don’t often see that on web forums.
