Bov

Just wondering if any knows if i were to put a perrin recirculating BOV on my car if it would mess up my tune at all

 

Im not positive but I think they should be configured into the tune...

 

should be fine if it doesn't leak. it won't mess up your 'tune', just your 'engine'

the factory bypass valve accomplishes the same thing

 

yes it "can"

 

if you need the factory valve to hold more boost, either take a huge hammer or find a way to crush the top a bit

or here is a much more precise way that member Wolfplayer incorporates from iwsti
