i'm looking into picking up some gauge to moniter my new motor that will be goin in the stang come spring, i tried to search this but found no help really. whats the big difference with autometer compared to sunpro gauges? i can pick up like 3 different sunpro ones for the price of one autometer gauge. is there any real quality differences?...... what do you all think?.......... may be a dumb question but i can't figure why the autometer ones would be so much better, after all they are just gauges right?
