Guys,

Three questions on this subject:

1) Will OPC find them easily when servicing, therefore voiding my warranty?
2) How does it effect performance, re-map ECU vs standard?
3) Best brand out there for quality and reliability..?

 

They dont leak boost like the stock ones can. OPC cant void the warranty. Best are Baileys, EVO, or another billet valve.

 

what are they?

 

they help u get rid of ur turbo lag , i got the hyperboost DVs and trust me u would feel the difference mmm about the warrenty they ddnt void mine

 

in kuwait they will void your warrenty according to bh bh motors.who installed yours.

 

but they ddnt void mine
