Thanks for getting back to me. I'm in Queensland Australia so I suspect it is best for me to contact CT Cars and find out more about the chip itself then I'll look around for an Australian supplier. I must say that my son's Amarok seems to have lots more power which is transmitted through a conventional 6 speed automatic which seems counterintuitive as the DSG should in theory provide a more direct power delivery. They both share what is essentially the same motor; ie VW 2.0 litre turbo diesel.
As an aside, almost bogged the Yeti in Western Queensland last week with mud so sticky that the wheel arches became packed, elimination suspension and steering movement. Gearbox alarmed on overheat and with 10PSI in tyres plus lots of patience, finally managed to retreat from a very 'sticky' situation.
Kind regards
