A bit more information for everybody...
I'm not preaching from a mountain top about this stuff; I just think the design seems excellent in
theory. Application is a different story. I thought all of you might want to see it too.
Anyway, there is pretty detailed information regarding the material composition of the WG, so I would wager the BOV is similar...

Materials
*Investment-cast stainless steel 304 for exhaust valve housing
*Al 6061 T6 for actuator housing
*High temp engineered axial contact polymer seals
*Self-lubricating Carbon Kevlar valve seal
The current philosophy is to use exotic materials, and voila your wastegate is now better. Or perhaps use exotic materials to band-aid problems like sticking valves. Our approach is to have a fundamentally sound design first, and then select the appropriate materials. We don’t want to take a bad design and simply improve it with better manufacturing and better materials. We truly want to bring you prototypical innovation, by design.
The use of 304SS for the valve housing will allow for a good mix of Nickel and Chromium content for thermal insulation, resistance to creep deformation, corrosion and high temperatures. We decided against the use of 254MA or 347SS for the casting due to the high Nickel and low Chromium content. Yes, these materials have higher strength at elevated temperatures, but they aren’t being used as stressed structural members, thereby eliminating the need for strength. 347SS and 254MA’s melting points are close to that of 304SS, which is what matters. More importantly, these materials are very high in Nickel, and the higher the Nickel, the greater the factor for thermal expansion, meaning that the parts will grow at extreme temperatures. For the one-piece valve and valve seat we are testing a high Chromium, low Nickel 400 series stainless steel that can be treated for hardness. The Chromium stabilizes the steel at high operating temperatures, maintaining the critical tolerances in extreme service. It is no wonder that legacy designs have valve sticking problems, since Nitronic SS is a high Nickel SS with a high coefficient of thermal expansion. So as temperatures elevate, the parts grow and bind with each other. Our material selection seeks to eliminate this problem. In addition, the valve stem seal used in the Synchronic wastegate will neither gall nor bind with steel at any temperature. In fact, it has a higher melting temperature than the seal, and self lubricates.
We really don’t care what material the competition uses in their diaphragms because we’ve eliminated the diaphragm altogether by using engineered polymer seals to insure sealing between the 4 unique actuation chambers of the Synchronic actuator geometry. You may have heard of other manufacturers that require special coatings to mitigate binding and sticking of their valves. This screams band-aid. Synchronic WG has no valve guide and uses the actuator geometry to guide the valve and is designed to self-center as pneumatic pressure increases.

Sorry I couldn't do a legit spreadsheet, but I think you all can figure out what corresponds with what.
Introductory MSRP on the BOV is
$219, and yes, there is a V-band kit for the WG.
