Hey guys
I've had the Turbosmart Dual Port BPV fitted for about 18 months. I have it half recirc and half vent to air. The car was in for service last week and had the air filter changed.
Since I picked the car up, I've noticed something strange that I would like some comments on - The BPV seems to vent twice in quick succession when you change gears or lift off at mid or full throttle. If I remember rightly, it only vented once before.
I think the workshop have tightened the BPV spring tension when it was in there?

Just to ad to that so you know what I mean, rather than making one big Pssssht sound at each gear change, it is going psssht psssht.
Does anyone know if this means it is overtensioned?
