Was driving today, pyro seemed to be accuate. Was sitting and idleing, and pyro jumped to 1229, then down to 31, and stayed there. When I'm driving at 65, just cruising, it fluxuates from 450-900, like crazy, anyone had this happen?? Box is only 2 months old!! Gonna be ****** if i have to send it back, for $850 bucks they better pay shipping!! Not a happy camper.

My analog gauge acted that way and it was only the screw connection where the wires came together, check those.

Checked all connections, all is well. Guess I'll send it back, God only knows how long they will have it.

Mine did the same thing twice and had to send it back for a new one

do you put a spark plug in the pryo hole while it's gone?

Talked to TST today, they are sending me a new thermocouple, they don't think it is the box itelf, guess we will wait and see. sucks not knowing what your EGTs are.

Every once in awhile I pull pryro coupler from the manifold and clean it off. It is amazing how much carbon collects on it. I would imagine that after a while the reading might be thrown off by the carbon.
