Those of us who purchased Prosport gauges here locally in Phoenix had to install additional grounds to the senders because of accuracy problems. It made as much as 10 degrees difference in the temperature the gauges were reporting.

Chickenwafer had this problem and contacted Prosport about it. I PM'd him to find out what he had to do when I realized my gauges were off. Here's what he sent which is basically reiterating what Flashwing was saying:

I ran another ground wire from a chassis ground (one near the OEM windshield washer bottle, on the passenger side fender area, there are a few other wires grounded there) to the ground wire coming off the water temp sensor.
I verified with my multimeter 0ohms doing this. It made the water temp readings much more accurate, but it is still off at the higher end of the scale (gauge reads 180F when coolant is really 185-187ish, from the AccessPORT). Then again it's also rumored the OEM coolant temp sensor reads +5 degrees F.
I am using the Racing Beat temp adapter which places the sensor in the heater hose which isn't exactly ideal, IMHO. If I could do it again I would put it in the top radiator hose (which I will do at a later date).

It doesn't matter Brice. The grounds on the premium still allow up to 10 ohms. I'm redoing the grounds on mine next time I get under the hood.

What about which gauges you guy's are installing in your cars.....I have 7 locations 
but I really would like 8 gauges, I need to eliminate one.....Prosport Premiums, I'm thinking to eliminate either one of the last 2, but I'm really open to suggestion....eventually will be boost with a supercharger...
-Oil Pressure
-Oil Temp
-Water Temp
-Boost (for the near future
-Wideband Fuel/Air Ratio
-Voltmeter
-EGT
-Fuel Pressure

I have the vent pod and RB lower ashtray replacement and soon the Nav panel 3 pods group buy.... so no pillar for this guy
Ya I'm thinking the voltmeter as well but is the EGT really useful for the Boost application? I fly with Turbine engine and yes a sort of EGT (TIT) and it is very important for us...but for a car?
For the electrical System on the other we really have little warning of a problem??

If an adapter was put in the upper radiator hose the 2 readings would be much closer.
