It's time for one. Finally. I'm looking at the Autometer MIni ultra-lite ATM-4301. Does anyone reccomend any other guage??? I would Like it to be white faced, 2" and hopefully one that goes to 25-30Psi in boost. So far I found ones that go up to 30 PSI, but those have a vacuum readout. Do I really need the vacuum readout??? thanx -Max V. 92 Ty
