Is there any performance gain with DV's?

Drakos · 07-17-2009, 01:00 AM

I have been considering picking up a set of Forge DV's but don't know if there would be any performance gain. I have an auto so would that nullify the need for an aftermarket DV? I read somewhere once that bov's are a waste of money on autos.

I lost power on the dyno with DV's. It was because the stock rubber hose was not a tight enough seal.

no, they will just help hold more boost.

you wont gain power, but they could keep you from losing power due to the stock parts leaking.

also better on/off throttle transitions I found.
