Safely I would say 1250, but I've hit 1350 a few times and nothing bad yet. I won't go over that though.

1200 is where I back out or drop to a less tune.

to help control them there are a few things to do. bigger exhaust housing on the turbo, free flowing exhaust, better or less powerful tunes, water injection, intercooler upgrades

then there are the big boy upgrades like bigger, better turbo and injectors but that costs more then I can afford.

Just a basic 01 F350 CCLB SRW -Good from a far but far from good

It is best advised to not be over 1250 for extended intervals. You may, depending on what/how you tow, be over that amount but practice not to be over 1250 beyond a minute.

Interesting to see some folks have been way up as high as 1500 or so, and that probably won't hurt but I wouldn't sustain those temps for over a minute or so

Time has as much to do with it as temp does.
1500 for a few seconds
1200 sustained

Make sure you have the temp probe pre-turbo, putting it in the down pipe aint no good and that’s what a lot of folks do. Post turbo temps are a completely different thing.

I have never heard this. What temps are you looking for if your eGT is right in the beginning of the down pipe?

2005 350 SDSC 4x4 Auto 6.0h no

Mods
turbo back exhaust, EGR delete, GPS, DVD, MP3
Privacy glass

For now.............................
