    Car leaking boost????

    I just had phase 1 remap and dump valve fitted. All was fine then friday night i was driving and it doesnt respond like it should and its eatting fuel. Sounds like it could be leaking boost?Ive got to take it back to regal on wednesday to have them look at it.Any other ideas what it could be?

    as you said, air leak. Check all the vacuum hoses, tighten all the clips etc. I use the 1 way valve trick, if its the wrong way round, ie the OE DV doesnt get any boost pressure it stays open and drives like a bag of W£"K. Having a aftermarket DV will increase fuel consumption..... think about it, air is metered into the system, the fueling is sorted out, then you take out the air, the fuel will still be the same amount as when the air was first metered, but you loose all the air, so mega rich mixture, resulting in pop, bang, overfueling, smelling of fuel from the mota, increased fuel consumption. I still use my HKS DV all the same!
