I'll agree with the fastest reacting part although the part about being the best is true BS!
I had three first gen. $PA combination gauges (installed April 2000)...
Fuel Press. /Oil Temp.
Boost/EGT
Trans. Temp. /Rear End Temp.
The Fuel Press. /Oil Temp. gauge had all the LED(s) (internal, i. e. , NOT replaceable!) burn out, and the Boost/EGT gauge died completely! I agreed to upgrade my "old" $PA gauges to the newer (and better

) Mark II series, being assured that all the problems had been taken care of.
The $PA Mark II series gauges were even nicer and more user friendly than their previous offerings however, that's where it ended! I had more burnt out LEDs, sending them back repeatedly for warranty replacement, all the while being assured that the LED problems had been taken care of.
Finally, I said, to he!! with it and decided to bail.
After much research, I decided to go with the Autometer Sport Comp gauges specially made for Diesel Dynamics. BTW, their gauges have the black face, white markings, bright red/orange needle with a black bezel... and no, they aren't Z Series. I have their 0-60 PSI boost gauge, their 0-1,600 degree F. pyrometer, their 140-300 degree F. trans. temp. gauge, and their 0-35 PSI mechanical fuel press. gauge. Very nice looking, with parameters that are tailored to our Cummins TDs. Now I just have to find the time to install them.
