Hi Dave,

Truth be told I don't understand that area enough to imagine things like that, its why I asked so that I could understand it better so I appreciate the information. Out of curiousity though, how does the increased boost pressure cause the vapour when I leave the car to warm up? My vapour occurs regardless of whether I drive it or not so boost pressure wouldn't factor.in yet would it?
