I've been running their tuning on my 17 for about a month now. Set on the 550 for the majority of the time. Shifting is perfect. Power is great. I've always run their tuning. Always been happy with it.
From what I was told, yes. Engineer said the two biggest complaints for his department were the noise the low pressure pump made and tank size. Guess they solved both of those.
I agree. There isn't anything online anywhere saying "yay" or "nay" for our trucks. There is a bunch of stuff saying "yay" for the TDI VWs. Just nothing on a 6.7 or LML D/Max.
