EGT Temperatures
I have a 1997 F250 7.3 with some work done to it. It's got an electric fuel system, exhaust, turbo pedestal, and bigger injectors. The injectors are rosewood 160/0. It's also got jelibuilt tunes on a hydra tuner. I'm looking to add more power and use more of the fuel I already have. I'm just scared of running too high egt's without an egt gauge. I'd like to get a KC stage 1 or 2 turbo, or even rebuild a stock turbo with different housings and compressor wheel. Does anyone have a similar setup? I'd love to intercool the truck but I'm not sure if it's necessary at this point. If someone can point me in the correct direction to start off, I'm open to suggestions.

If you run a tune, you need EGT monitoring... You just do not know without gauges. Every setup, the same setup as your buddy will run different from engine to engine.
No intercooler not a good idea with a chip and no EGT.
It takes an afternoon to add a simple EGT setup. Just do it.
If you run bone stock 7.3 at max loaded output, possibly (slight chance) you would want EGT monitoring even then.

Stock injectors at altitude and aggressive tuning are enough to melt pistons. A charge air cooler or "intercooler" is an absolute necessity if you plan on using your pickup with 160's. That should be your next modification (including a pyrometer).

I have a similar setup and on a hot tune with a steep or long incline you can approach high egts. I have had to back off the accelerator pedal a couple times. I recommend installing a gauge at the manifold and not at the down pipe

Don’t want to hijack this guys thread. But do you ever see much difference between the two sides? Or is it more for diagnosing/catching a failure in one bank vs the other?

One person had a 100 degree difference between sides and let them know something was wrong. Might have been Glen, he tows heavy
