Stumbled across this on the tube. Certainly just adds to the misinformation that is VW it seems. There is no doubt the T6 Turbo/EGR etc is very different to the earlier T5/5.1 era set up as confirmed by VW Guru when he was around. Short of it is the 199 is the least stressed of these units so consequently has the most tuning headroom.
