Do I have to have a dump valve?

[Stuart 528]

Noticed how everyone on here seems to have dump valves fitted when tuning the beeza cupra, I hate dump valves with a passion but are they required for higher engine tuning??

Is the standard set up a recirc?

All you have to do mate is get the forge 007dv as its quiet. They do help with the boost as the standard bosch ones are weak

Your car has re-circulating valve which is the same as a forge 007p but the original plastic one is v.poor quality so you need to uprate it if your going to tune your engine. The split-r forge do is a dump and re-circulte valve so I wouldnt get one of those if you dont like the sound but the 007p will make a noise with an open cone.
