Don't worry - not the normal questions on how to fit etc....;)

The recent thread on 'gadgets' has got me thinking again, and time to fit a boost gauge to make sure all is well under the bonnet with the turbo (as recently been having my doubts :().

I know the 'normal' disco boosts to around 1 bar or 15 psi, so should I be ok with a gauge upto 20 psi?

What range have others gone for?

Also as the diesel engines don't produce a vacuum, I have tried to find a gauge without this part, but seems all those ones are silly money - anyone found a decent priced one, or have people just fitted the normal type gauge (with the vacuum part) and not found any issues?

Cheers
