My old man is wanting to upgrade his gauges in his 99 cummins dually 6spd and told me he would basically give me the gauges in there now. which is a killer deal for me. its an isspro pyrometer and another. for the life of me i cant remember what it is white faces with blue needles.

The catch is that the pyro sticks at about 400. Is there a way to fix this? Or is it junk?

i have sent factory gauges to redline in california for re calibration and have had very good luck with them.

This could also be a bad pyro tip. Check it against a good one. Maybe you get lucky.
