turbosmart dump valves

[vw_nutta]

I've just fitted some to my s4.

They don't make alot of noise? is this normal?, most of my mates turbo cars are "tishing" about in every gear, I can hardly hear mine?

They're the adjustable ones and I think I've fitted them right, anyone got any tips?

I also want to get a boost gauge but how do you fit one in terms of plumbing it in?

thanks.

Are they the dual port type??
