    If you have the hoses the wrong way it will run like a bag of s*** and you will notice a differance when boosting it may be the actual electrovalve is knackerd internally try disconnecting it and see if it goes if it does I'd say it's knackerd !!

    I don't think the N75 is capable of making that noise, and if either N75 wasn't happy you'd have major (like 0%) boost issues. I dunno what the electrovalve is (maybe a dodgey 80's band?) Maybe something has worked loose and rubbing against a moving part?
