Yip Scoobymania supply Defi guages.
I also took delivery of a set a couple of days ago from them, oil temp, oil pressure, turbo and control unit II
Excellent stuff
I got a set of 3 from Scoobymania in Nottingham: boost, oil temperature, oil pressure, plus their pod, and the control box, with an adaptor for the oil temp gauge for £450 or thereabouts last June.
Give them a try.
