Dillz Three pedals are better then two.. Donating Members 15,637 Member For: 17y 6m 28d Gender: Male Location: Melbourne Posted 05/09/07 06:31 AM Share Posted 05/09/07 06:31 AM Remember Ford recommend that you don't modify your car either to save themself on warranty claims. I would say there would be a similar motive behind Garrett recommending BOV's. Anything that reduces wear and tear on a turbo reduces their warranty claims...Just a thoughtChrisI'm confused, I swear the other bov post going on atm says that BOVs are bad for your turbo and just there for noise, And to remove it all together.

A K&N with std boost will produce a little noise. I.e. turkey gobble. The BOV may have been leaking boost... there is a possibility if you block the vacuum which would otherwise definately keep the valve closed when on boost.

SHOWDOWN BACK SLOWER THEN EVER!

Sounded mighty sweet this evening, noticable better throttle response. Still too early to tell, could be the placebo...Has anyone had an instance of the chair rubbers melting? That is my fear. I'll keep an eye on it.Ozziep.s. I have an auto, in case you were wondering Link to comment Share on other sites More sharing options...
