Glowshift Gauges are complete GARBAGE. I had 6 of them on the shelf for a couple years then installed them on a customer truck and only one worked. The others were either WRONG or just not functioning.

Bought....

- dual air pressure

- battery voltage

- transmission temp

- fuel level

- low rail psi

- high rail psi

The only one that was even close to accurate was the Voltage on an auxiliary battery. By close, it was OFF BY 2 VOLTS.

The other 5 were just wrong when tested. PURE JUNK

In addition the high rail pressure unit caused a P0193 code that would not go away. It also created a misreading of rail pressure from the OBD scanner.

The Low pressure unit was just stuck on 30psi......had to install an inline Autometer to test the function.



IT IS CHINESE GARBAGE...not reliable just lights that don't even stay on the level set.

 

Very nice car! How long have you had it ?
