If you are getting a psssh, air is probably going where it isn't supposed to.

You should remove them and pressure test them.

They are EVOMS DV's. Yes, I am familiar with what DV's do, and the reason I can hear them is because of the V-flow. When shifting and the TB shuts, all that charged air goes thru the DV's and back into the intake plenum. Since the filter on the V-flow is very near where the DV's route the charged air, that is why it's more audible. Before I put the V-flow on, I could never hear them working.

Seal Grey Matte is a splendid one to behold

Sorry if I was a bit pedantic there. The honking really gives me a concern though. At very least, the internal piston probably needs to be lubricated. If it were me, I'd still pressure test them.

By the way Softronic has standard flashes and custom tuned flashes. These are sold by many different distributors and some labeled as there own also.

Oh no, not another Flash War!

My rule of thumb is... never say anything bad about anything unless you experienced it yourself.

"Then again you already have another agenda" +1.

No worries. I'm 99.99% sure it's the V-flow, and I have heard others say the same thing after installing a V-flow. I will lubricate my DV's though...any idea what to lube them with???

Yes it's the V-flow,I can hear mine DV's very good because I have an open air filter and when I put stock airbox in I don't hear them at all...

I think Forge recommends Mobil 1 synthetic grease. Good luck! If you're going to go through the trouble of cracking them open to service them, you might as well pressure test them too. You don't need any special equipment aside from the palm of your hand.

Diverter valves are necessary at the increased boost. Vivid Racing uses Forge Motorsport valves the original one everyone has copied

Why would you say stay away from Softronic? Softronic is one of the best ECU flashes available. I have used 3 different companies myself. I would gladly discuss them with you on the phone.
