From Porsche development guys to me:

Regarding the GT2RS engine, yes it is likely to be the final use of the Metzger 3.6 litre engine, simply because it meets EU4 emission standards, rather than EU5. The 3.6 and 3.8-litre DFI engines meet EU5 already.

P.S. the flow test was made from AWE tuning...if i can recall right...I will do a search about it...
Just found it,its on the video of the Champion Motorsport ICs,where flow test was applied to 997TT and 997,2TT ICs...

and here they are (way more dense which would explain a slight drop in flow):
