GFB Diverter Valve 2020 R-Line Tiguan

Has anyone fitted a GFB T9351 diverter valve with an upgraded turbo intake?
Does look like there is enough room.

Depending on which intake pipe you have, the GFB valve may not fit. I saw on a video the other day that they have just released a brand new DV valve for VW which is shorter in length which will fit. (although it looks like its not on their website yet).

Forward to about 17.00 minutes in this video to see it

Your right, just spoke to GFB the complete diverter valve is not on sale yet, due early 2023. MCM got the prototype.

Hi just checking if there has been any update on the new complete diverter valve?

I fitted the new T9381 DV+ to my Tig RLine today. Easy job, the slightly shorter length compared to the stock one helped when I put an aftermarket intake pipe as well

Thanks for the update - what aftermarket intake pipe did you go with?

Leyo Motorsports
the MQB version that fits the mk7 golf, pod filter, metal pipe and air box.

Finally got my new GFB diverter valve & fitted it, very simple job 15mins.
Interesting how much its changed the delivery of power with my bigger turbo & tune (the std valve must have been leaking).
Worth every cent!

Which GFB model did you install? Has it done much to improve the throttle response (as advertised)?

My stage 2 Arteon is a bit laggy on the throttle and seems to be letting out little bursts of boost when accelerating moderately hard... might be normal, or possibly traction control cutting power maybe. Been looking into the diverter valve as a possible culprit and candidate for upgrade.
