Ive read so may different threads on replacing the standard bov and so confused now I really dont know what to believe?

Should it be changed or kept standard?
Does it need to be changed on being remapped?
Which is the correct/peferred one if so?

 

Keep the standard one on.

 

Agreed standard one is more than adequate I decided to change mine for a turbosmart blow off valve lasted a week went back to standard one

 

standard one will do the job unless your setup is extreme - if you want a bit more noise you can switch it out for a quality aftermarket one. Note the "quality" bit there - a 10.99 one off ebay will give you terrible running problems but a genuine good quality unit will work just fine.

 

Any one in particular?

 

i've had good success with genuine HKS SSQV (watch out there are a lot of copies about that suck), forge and Bailey DV12. Plenty of horror stories about the ebay crap ones though

 

Thanks buddy will take a look.

 

if you have any doubt about the standard bov leaking -blank off the outlet hose-
if boost increases replace it

was thinking of getting the hks ssqv but was wondering if i need to get it remapped or not?
