^^ According to others the boost gauge seems inaccurate, it won't display negative values and the boost pressure doesn't convert atmospheric pressure, so it reads something silly like 30psi, which it isn't at all.
The only thing that needs to be looked at is the revs... and the speedo of course.

Anything displayed below and to the left of your line of sight is a waste of time unless some feel its possible to view data in real time constantly while driving.
Nice to have on a new model for fun value though, to show people, I wouldn't mind it. But I would want to rely on it or think its accurate
