I am planning on some 5" quad gauges for my truck soon and have seen them from autometer, dolphin, and classic instruments. Then today I saw some made by a company called tpi-tech that look pretty good and have great features. Also they say they are made here in the U.S.A which makes me like them even more. Im just looking for some history on them would like to here if anyone out there has tried them or knew someone that has. Im pretty much sold on them so far.
