Can't beat the weekly dump valve thread which has gone on for ten
Years now
Good to atract teenage birds at McDonalds car parks
Which will fast track you into fatherhood ,free council house
And rearward facing baseball caps and cheap Argos rings for Xmas
And oversized trainers and track suits
Are you really sure you want a dump valve
Ppppssssstttttttt

 

+1 ,it would be easier to just use the search bar imho,and save repeat post on a subject that is down to personal preference.

If you want a noise then buy one otherwise the std will do fine. You wont gain any performance by fitting one so whats the point imho .

 

Quite right, had a very thick moment. apologies. Meant dump valve is after maf sensor, so will be dumping air giving less air to mixture than Ecu thinks it is supplying so making car run rich. Doh.
