Before considering any #'s tell us a little more about what you have, is it stock?

Melting point of Al = 1220 degrees. It is alright (pre-turbo) to get to 1250 for a few seconds, but then you need to back off and keep it below 1100.

Stock truck other then cat and muffler delete, soon to have a 3" downpipe and 4" exhaust however. Probe is in the left manifold just before the connector to the pipe.
I did just do a cold air intake a couple days ago but haven't noticed a difference.

I have been seeing 600-800 cruising unloaded, passing somebody or getting on it up hill with no load have seen 1050-1100.

Haven't towed with it yet since the egt install, next weekend will be first trip. I have since installed a boost gauge. Cruising it makes maybe 1-3 psi, jumping on the throttle I have seen a max of 16 psi.

Truck is a 97 powerstroke with 230K with an auto, just installed the SOnnax spring kit and valve in the valve body.

Sounds good. Just don't keep it over 1100 sustained. 1250 is ok for a short burst.

Well I now have a 3" down pipe, 4" straight back to the axle, then a 4" tailpipe up and over.

The DOWN PIPE SUCKED

I also have a leak in the exhaust pipe between the manifolds and the turbo. Once the down pipe was out I could see the black marks around the flange showing the leak. Have to deal with that another day.

Temps should drop. Did your factory down pipe seem/look restrictive?

The OBS downpipe is restrictive. Good move ditching it. The Superduty downpipe isn't as bad considering it is stock.

Do you have a chip?

I can push 1200+ pretty easy towing.

But the shift points of the trans are off and the torque convertor is dieing a slow death.

How much boost when your EGTs are at 1200?

You actually want higher boost when your EGTs start to rise. It clears out the heat. Lugging the engine causes higher EGTs.

I see about 20psi max but when around 1200 its typically around 12-14, I have learned to control the egts since the orig post. With the trans teh way it is its a challenge lol.

His seems kinda high for being stock tuning. In my 80HP Econo setting I have to push it fairly hard to hit 1200.
