I spose ill ask a semi Noob question. Now that I have the C.A.I. on, I can hear the DV very very well now. I remember asking a while back if the DV should Always flutter or at higher rpms just go PSSSHHHH. Well, mine ONLY does the flutter sound unless I smash the gas to redline (to me, that doesnt seem normal AND even then it's questionable if it'll just go pssh. Usually just a loud flutter). I still havent put the Forge on yet since "Professor, turbo, hot." I've been told OEM DV's have a rubber diaphram which is known to rip? could this be the cause of constant flutter?

Hopefully once I get the Forge on there it will work properly. Heading through an underpass lastnight in victor when I downshifted to third then punched it, the 3-4th shift I could hear just a normal PSSSHH. But thats the Only time it's done it.

 

This is what I was expecting the OEM one to sound like. However this gives me high hopes for the Forge one now =)

most will flutter with a low amount of boost (~5psi) and be clean over that.

 

So I finally put the Forge on about 20 minutes ago. I put Only the green spring in there, shimless. What a huge improvement. Drives better, accelerates better. Everything better. OEM valve must have been goofed up since this one sounds just like in the vid I posted. No flutter, clean pssshh sound. Now for the "Tuneing" process.
How will I know if I need to add a shim/different spring into the DV? (I have no boost gauge at this given moment) Is it doable by ear/driving to know if I have got it spot on.

 

in everyones opinion whats the best DV valve to get... and where's the cheapest place to order it?

 

Yes, you want the lowest spring value that does not flutter while under load. However, may I suggest your next mod be a boost guage? They are failry inexpensive and are awesome for trouble shooting other issues if they occur later on.

 

Yea boost gauge is next on the list. Need to pick a size and find a pod to work with. I don't totally want to lose a vent for a gauge...but eh....Maybe. And Right now there is no flutter at all. I'll add a shim tomorrow when everythings not too hot to handle and see how it goes.
