I had installed Pyro, Boost and trans temp gauges in my new truck. Now my question is, What is the normal ranges for this three gauges. Normal driving versus towing trailer (9,000lbs). I know that is not a standard range, but what is at least normal before I have to worry about it. Thank you all.

 

Very hard to answer.
Pyro...Depends on how it is installed (in the manifold, or in the down pipe)
Tranny Temp...Depends on how it is installed.
Boost...Depends on how heavy your foot is. With a stock 04 engine, you will prob ally not see over 22 or 23. An 04.5 I think will be a little higher.

 

Pyro, most likely normal would be 600-900 cruising empty.
Don't want it over 1300 if pre turbo, 800 if post turbo, for any extended length of time.
I've seen 1250 running empty, flooring it.

Tranny temp, 270ish is when the warning light on the dash comes on,
at that point it's pull over and call a towtruck, tranny is toasted.
Mine, in the hot line to the cooler, runs 160ish cruising, have seen up to 190 stuck in stop-go traffic, 230 hillclimbing offroad.

Boost, 10 cruising, 19-21 WOT, as that is where it is most likely wastegated.

Being that mine is a 2nd gen 2002, number might vary slightly.
