I don't think I've ever heard flutter at full throttle. If i down shift to 5th gear i have no sound with the same amount of boost. It all depends sometimes these cars have alil flutter stock, but it all depends exactly what kind of flutter and how excessive it is, alot of times they have alil wastegate flutter at lower rpms with like mid boost or so. ![]() This only happens in 6th gear under a hard load like pulling my trailer up a hill. ![]() The diaphragm reacts to pressure changes and in a predetermined vacuum, it’s pulled toward the vacuum source compressing the spring inside the housing.
