I got my pyro, vacum, and boost, and pillar mount from summit racing. Really nice gauges and easy install. If memory serves, pyro was like $170. The gauges were autometer. phatom II series, I believe

It measures your EGT's (exuast gas temp) and from what i've been told the exaust manifold is the best most acurate spot. You'll have to drill and tap the manifold for the thermocouple.

I bought mine here:
Auto Meter (AutoMeter) Gauges from egauges.com
Good selection and I have had good service.
On my '88 I drilled and tapped about half way between the front two cylinders on the driver side exhaust manifold. haven't restarted the truck yet so can't speak to the rest of the install but it looks pretty straight forward to me.

I'm happy with my autometers but the color codeing on the ISSPROs is nice.

Piston damage can start at 1250 degrees.
So if the thermocouple is in the exhaust manifold, keep the EGT below 1200 degrees max to give yourself a little margin for error.
If you are pulling up the Rockies or a steep hill several miles long, keep it a bit lower because it is going to be there for a while.
When I get on some of our hills here, very steep grades, I keep mine between 1100 and 1150.
