Ok I've read all I can and have got to the point where need to decide between Autometer Cobalt or Top End Audio Gauges. I can get Oil Pressure, Fuel Pressure and Boost for both brands for about $1,000 with the triple gauge holder. Both seem to be made in the USA. They both have the right colour though the TEA has a warning light. TEA gauges come with 5 year warranty on the senders, which I think exceeds the Cobalt ones. However the Autometer come with a great reputation. I don't know much about the TEA longevity. What is peoples thoughts. I just want something that I can install and know it will work. I had Ozigauges in my old car though I had no end of trouble with the Oil Pressure sender. I went through three of them.
