guages

A quick question for you all, I have a ported and mill set of heads, hot cam, 1.6rr, hypertech chip, 160 deg therm., fuel pressure reg., msd 6al box., msd 8.5 wires, a/c delco plugs, lt-4 timing chain, under pulley, 3" flowmaster exhaust, cai, my only guage I have is a fuel pressure guage what other guages should i use to monitor my engine safely. My future mod's coming up will be a set of long tube headers, and a bigger throttle body. I just want to keep a track of the engines performance so I can monitor everthing. WHAT guages is everyone using right now and for what purpose. Any info. from anyone would be grateful. :confused:

could always get some wideband O2 sensors if you have the money, tranny temp, oil temp..

The stock gauges aren't all that bad, except for the tach. Anything I've added, other than an oil pressure gauge, is to get info from things that the factory gauges can't provide... fuel pressure, nitrous pressure, oil temp and trans temp.
