I'd get one in PSI tbh, bar isn't easy to read at a glance. You don't need vacuum either on a diesel boost gauge, so not sure why they're saying that's HDi specific at all lol.
Basically, any gauge will work, it's just down to preference I guess, and accuracy should be better on higher quality ones.
