Engine/Transmission (1998.5 - 2002) Guages - Your Info

[CCCRAM]

Hey Gang!



I installed Westach guages recently and want to find out what "average" readings should be so I can tell how my rig is working. My guage readings are at 65mph on hwy after full warm up:



EGT/BOOST: Combo gauge reading EGT: 800 or so, and Boost, 12-15



COMBO TEMP GUAGE: Rear differential: around 100 degrees, transmission 125 degrees



FUEL PRESSURE: Around 8 psi



What's yours?



What differences should I see at WOT?

What about going up a hill, say 6% grade, w/o load?

How about under load (5er, 8000#)



Thanks for the info!

I see 14-17 psi of Boost and 12-12. 5 psi of fuel pressure. Your fuel number seems real low. I think DC has an 8psi min spec on the fuel pressures. Low FP usually means dying lift pump.
