what do you guys think would best go with a vac-boost gauge from autometer for a dual a-pillar pod for a supercharger. i was thinking either a air/fuel gauge or a pyrometer, or both. they both do the same thing but the pyrometer is less annoying and a little more accurate. I am planning on getting the c2 gauges from autometer and the vac boost gauge and pyrometer are $160 and the air fuel gauge is like 75. so what do u guys think?
