I assume you mean "Forge" as in the brand...? If so, what sort of noise is it making? Maybe just put a different spring in it.

My guess is the spring that came installed in the valve isn't stiff enough. Try a heavier one.

a noise...can you be a little more specific. i suspect its just the bov leaking under higher boost. which would just mean you need a stiffer spring.

Did you get the Forge 'Eliminator' valve? It is stainless steel (and bigger than stock) but still uses a diaphragm, so it will make that 'hoot' noise the stock makes sometimes. It is the Forge 007PA that is the piston valve that eliminates that sound entirely.

i believe its the Forge eliminator with the rubber diaphram. so its normal to sometimes hear the "hoot" sound? just worried i might be loosing some boost

I believe the noise is normal. The diaphragm may be wearing out though and need replacement. If you call up Forge they will send you a crapload of replacement parts for free, just in case you are worried. The Eliminator is supposed to be a bit faster than the 007PA piston valve because the diaphragm is so lightweight, I personally run the 007PA and have had no problems, but the Eliminator has gotten very high reviews.
