Well my pyro gauge from IssPro is acting up. It hits 550* then nosedives to zero. Called Diesel Manor who I purchased it from in April 2006 and they are going to have IssPro send me a new amplifier box at no charge. Great customer service from them, explained my issue and they corrected right then.

 

i am on my third amp box for my tranny gauges ( i have two) i also have had a probe replaced- all since march. i now have another bad amp box- diesel manor is referring my problem to isspro. i went with isspro because i had nothing but problems with autometer-but isppro has been no better.

 

I asked the guy at Diesel Manor if the Pyro was a "matched" set. He said that the trans temp gauge was. You may want to ask them about that. Sorry, I should have got the guys name. I called them today around 1:30 PST.
