Just wrapped up installing my pyro gauge and let the truck idle for about 20 min. Gauge never really moved. Climbed to 300* when I cranked it and never moved. I am going to take it driving around to see if it changes but does this seem accurate?

 

Seems about right....it will move when you push that lil pedal with that right foot.

 

Boy does it ever move when you press that skinny little pedal.

 

After my test drive last night I feel much better. I did not drive it hard just around town and a bit on the interstate. Did not take it long to reach 600* and then 900*but never moved too far past 900*. Like I said it was normal driving but I never realized the temp changed so much so fast. Let off the pedal and it would drop from 900* to 600*. I am very happy with the gauge and now I just need to finish the others(FP, Boost, TransTemp) I need to buy parts for the rest and find some time away from work!!!
