Replacing the DVs is not meant to increase performance but rather reduce the possibility of them failing and thus reducing performance by leaking turbo boost...
But look at what you said; that failing valves reduce performance by leaking turbo boost. If there is "reduced performance" with bad valves, then replacing the bad valves with Baileys would "increase performance" back to the normal level.
My DVs were bad...they "honked". If they decreased my cars performance on anything but paper you could have fooled me, because I noticed no "increase or difference in performance" (i.e. back up to stock) with the Baileys installed. I'm talking seat of the pants difference.
I didn't have the Baileys installed as a "mod" to increase performance above stock, I replaced the valves because they were making noise, and I didn't want any degradation from stock performance. It turned out there wasn't any degradation in SOTP performance with the OEM "honking" valves.

OK, just got the car back with the new DV's replaced by Porsche under warranty...they are black so it is difficult to tell APPEAR to be metal as opposed to plastic....see the pic.
Prior to replacement, I could hit 1.0 bar (only mods are upsolute chip and a little tinkering with the stock exhaust), but it was a stretch and it would only hold for a second, and on the way home from the dealer tonight I hit 1.1 bar in 3rd gear and held it easily. Couldn't repeat due to traffic.

What kind of BS is this?
The 996 TT OFFICIALLY produces a maximum boost of 0.8 Bar

Of course, with this cooler weather, I am typically only seeing .6bar as I am sure that the ECU is adjusting to the higher O2 count in the cold(er) air.
