I replaced the OEM diverter valve today with a GFB DV+ T9381 - it's an all in one unit with solenoid that completely replaces the factory part.

The GFB DV+ is a more precisely engineered and shorter than the OEM DV (makes installation easier than OEM removal). The OEM DV piston is plastic and had a bit of play in it... Red piston clip on the DV+ has to be carefully removed prior to oiling and installation.

I think it was a worthwhile upgrade. There seems to be an improvement in throttle response - seems like a bit more torque is more readily available, feels like it builds/holds boost more readily and there are less turbo noises (the sounds have also changed somewhat).
The installation would have been a ~15 min job IF I had the right tools, but given that the larger/upgraded turbo elbow partially blocked the lower bolt, all my tool options wouldn't reach the lower bolt properly (top 2 were easy).. so, it actually took me over an hour (closer to 2 hours).

Would have been handy to have a universal joint extender for my socket, or maybe a perfectly-sized allen key (which I tried to make by hack-sawing a longer one)... so I made a franken-socket using a fence-screw drill driver/bit, a 1/4" socket and some electrical tape.. even though I had a telescopic magnet to fish out any dropped tools/screws, I still didn't want to try it out if possible (hence the electrical tape).

Anyhow, the steps were relatively simple:
- remove the inlet hose
- remove the OEM DV plug (has a tab to release first)
- undo the bolts (swear at that bottom bolt a few times - seems to help, make dodgy custom tools)
- remove the factory DV, add some oil (from the dipstick) to the GFB DV+ piston
- position and bolt in the DV+ in place
- connect the DV+ using the adapter/extension plug
- replace inlet hose
- test drive
