I know this is a noob question but I still can't figure out the difference(advantages) between Boost/Vacuum Gauge and Boost Gauge. Well I know the obvious difference is that the Boost/Vacuum has Vacuum shown on the left half of the gauge and Boost on the other half of the gauge. Basically I'm just wanting to know which one would be best to get for a FD. Getting (Electronic Full Sweep Gauge).

Thanks,

Engine vacuum is a great diagnostic tool, it can be used to diagnose vacuum/boost leaks, idle problems, low compression, the list goes on. I would get the boost and vacuum gauge if I were you. I bought a boost only gauge because it was $10 cheaper and ended up buying a vacuum/pressure gauge from advance for $20 because the car was running on 1 rotor.

 

Thank you for the insight. I guess I will be making a purchase for a Boost/Vacuum Gauge really soon.
