Best 60mm mech boost gauge for accuracy and reading on move?
 

As above really, looking for best gauge that's not to expensive that is good at getting accurate boost readings upto 2 bar.

Contact Bob Rawle, ask what one he uses for mapping, I know he doesn't rely on the car's one, whether Defi or other.

..........don't think Bob's is a 60mm one though, I don't remember it being that big, mind you half of my mind was occupied by looking at the road :)
