Need help with part selections of a Diverter Valve and a PCV.

Factory Diverter Valve may fail where the boost pressure has been increased by an ECU software upgrade. So need to choice a different DV to improved reliability.
The options for OEM Upgraded Piston Diverter Valve I find are

Forge Motorsport Replacement Valve for 2.0litre FSiT TFSi Engines
Forge Motorsport | Alloy Fabrication
AWE Tuning Diverter Valve - 2.0T - Mk5 G/J (06 - 09) - VW - PRODUCTS

Next part is the PCV or with Oil Catch Can too.
