Boost overshoots cannot be avoided. I expect that you have not driven in cold air yet. The whole point is to keep pressure off of the actuator and that means that the wastegate cannot be opened fast enough when the turbo is eager in cold air. Two balls? Me too! But can you explain what that means or post a URL. If the device was built with two ball-spring valves and one opened up a bit before the other, that might help quite a bit. I contempated a pressure regulator to apply a base pressure to the actuator so that it was ready to strke when the MBC opened up. But I build up a pop-off valve and that worked quite good.
I saw a MPG increase but, years after the MBC, that came with the 5W40 Delvac 1.
