I understand that. As far as I can read on forum, some suffer from the judder and some does not. Would I have bought the box, had I known there could be judder - 50/50, would I have bought it if it was definite that some kind of judder was to be expected, probably not. Would I like to go back today and drive without the DTUK box, nope - but I still wish I could run +1 maps without judder.ok so i was just about to order a DTUK for my 150tdi but seeing these judder problems is kind of putting me off slightly... now im in 2 minds weather to leave it standard or just go with my gut and buy 1.
So yes, it is pretty much up to your gut feeling
