My friend just bought a used F350, it is a 96 7.3 with an auto tranny. He put a downpipe, full exhaust, a super chip programer, and an intake. Also a EGT gauge and a trans temp gauge. My question is about what range should the EGT and trans gauge run at. Not sure of how high they should go? The EGT gauge will get up around 1200 towing up the grades which isn't a problem in the semis that I drive but I don't no if pickups are the same and I have no idea about trans temp. Thanks

1200 is about the max you wanna expose the turbo to for extended periods. The readings can vary a bit too whether or not your probe is pre, or post turbo.

The tranny temp gauge should read <100* above ambient, and you wanna keep it under 210-220 max.

Thanks, the temp gets to 1200 on the grades max and we kick it out of over drive and it drops to about 1000*. The probe is right after the turbo in the downpipe.

a true pyro temp is better place post turbo in the exhaust manifold. On powerstrokes its extremely easy to mount it on the driver manifold above the oil filter. Big rigs and most farm equipment are rigged this way. I bet your 1200* measurement is actually a few hundred degrees hotter.....scary.

1200* after the turbo is probably closer to 1700*-1900* pre turbo :eek:

don't you mean pre turbo?

The best area to measure is coming right out of the cylinders, ie.. pre turbo.

BUT post turbo is fine if you know what the limits are. 1200-1300 pre turbo is roughly 1000 post turbo (all depends on the engine, turbo, exhaust, etc)
