max psi for 20vt?

I've got the VDO 30lb gauge, it's fine for my mild chip which maxes at 15lbs, meaning at max the needle is straight up like a proper auto gauge needle should be.  However, VDO also makes a guage which measures a range of vacuum and pressure which I wish I had instead.  I think it measures -25 to +25.  The two benefits are:  now you are close to the full span of likely high boost readings, and 2) by measuring vacuum day in and out you can detect a leak earlier than otherwise.
