Ok i know nothing about gauges and probably dont need them... but i think they look cool and i would like to know how everything is running currently all i have done is cai tune and exhaust... My question is what gauges can i get baised on my current set up and how much would it run me also are there simple ones i could do myself? i mean i have done everything else myself so i can do most things involving wireing but i dont know how intensive it gets also i was thinking maybe 1 for voltage? seeing i run a pretty decent sound system... thanks for your help a head of time guys... please post pics and links as well!
