The hose wants to blow from the pressure which is the least path of resistance. The clamp purpose is to counter those forces. It is not possible for a clamp to make a full seal under any circumstances. If the hose has expanded due to oil contamination it will require a much higher clamping force that may leak at higher boost levels regardless and may not throw a code. I had this problem and now solved. There is not much to debate as this is a very well know issue that is mostly ignored by the aftermarket. One will need to do their own research to validate my comments instead of making assumtions.
