im running 3 autometers, only 1 is functioning at this time i will hook up the pyrometer (egt) and oil presure gauge at a later date. i have the ultra lite series that is silver. they seem to look fine. im not all about flashy gauges, and had i the tools and patience, i wouldnt have even gone with an apillar setup.
i think greddy and apexi are nice if you want the playback, i found these useful when checking boost and egt peaks when we were dyno tuning a car, because one had to watch the wideband and one had to watch the tach.
if i had an endless amount of money i would go with a DEFI gauge setup. the ultimate in electronic features (and ultimately the highest priced setups).
