    Dumpy help needed :(

    Ive just bought a dv26, and fitted it, but to my liking its too quiet . Ive put the vac pipe to the fuel pressure regulator like i know some people have, but also on this line i have my boost gauge.

    Now the dumpvalve seems to be slightly laggy and a bit too quiet. Ive read that some people take the vac pipe from their turbo, which controls the standard dv and put it to their baileys, and then blocked the standard dv.

    My question is, if i do that will it make the dumpy less laggy and will it be louder, as i also head that some people have had problems with doing it this way.

    Any help is appreciated. Cheers

    I've done it on mine and it's a big difference I first thought there would be hardly any but I was shocked how much louder it went! Well worth doing

    Do i have to block the standard dv on the turbo or can i just take the pipe off where it runs to and block that?

    I know that the tutorial tells you to take out the spring from the standard dv and replace it with a spacer, but if i just take the vac pipe off from the source at the back of the engine and block that, it will do that same job wont it?

    Put a one way valve in the vacuum line going to the standard dump valve
