Yep just sits there on zero, my turbo boost works great pyro sits there and does nothing any ideas?!!!!

 

Check the ground

 

Didnt install it so where is a common place the ground is well grounded?

 

You will need to check the ground wire on the gauge itself, check both while you are at it No telling where they ran the wiring, you are just going to have to look and find where they hooked it up.

It could be that your thermocouple or the gauge went bad, but a bad ground is a very real possibility Always check the easy stuff first

 

Ill see what i can do thanks...
