can anybody help?
iv just bought a scooby and would like to fit a dump valve? does any body know which is best and if i need a remap?

 

Alright mate, buy an HKS ssq dump valve.
This one has excellent build quality and has a sequential valve fitted...meaning it opens up less or more depending on the pressure being pushed through.
You willl not need a remap, although I felt a change in my power delivery after fitting.
I noticed that I got more grunt top end of the revs and a smoother feeling at lower revs.

Really easy to fit as well bro

 

It can disrupt the fuelling as the PPP is already a definded map, the dv can cause it to go lean then rich, too much of either is bad.
