gauges or electronic display?
Either way, Isspro builds a decent gauge, I had a set on my old truck, very easy to read. They seemed accurate from what I could tell and the price was fair enough.
I have DiPricol Optix TM now, I am happy with those also. Could have gone either way really, just preferred the look of the Optix pyro.
Don't have to have the Performax, they are just the newest they have to offer, and they seem to be designed with the mulitple gauges user in mind. I have the normal Isspros and they have been awesome also.
