Safe boost ?

[fireball]

What do you think is the max boost to be safe , i don't want to do the head job for now . when i tow my toyhauler it weight about 15k and climb a hill , what do you think i should see , i don't want to climb over 1200 deg on the EGT, and on the boost what's the max to be safe ?

Most guys running the SCT with custom tunes don't see much over 24-26 psi. These trucks stock can produce 25-30ish psi. If you have a custom tune you are safe on boost. Do you have any gauges?

[fireball]

Yes i have gauges , but do you think i can climb a hill go to about 25-26 on boost for maybe 30sec and be safe not to hammer the head gasket , tell if i can hit 30 on boost and be still be safe thanks

I wouldn't worry too much about hitting 25-26 psi even 30 psi for short periods. I don't know how much you have read about these 6.0 engines but some trucks are stretching headbolts and blowing headgaskets with everything completely stock. What year is your truck and is it still under warranty?

mine is a 2005 , the warranty is finish, but i tend to be light on the foot to keep it for long . that's why i want these info thanks !

You should be okay. Have you ever had any coolant blowing out of the degas/coolant reservoir?

fireball, dhanna6 has you pretty much covered. One thing to realize is that in stock trim these turbos can push enough air into the cylinder to stretch the bolts. Keeping it under 30psi is your best bet.

When I am towing up some nasty Arizona mountains I get close to 30 psi and stay there for 5 to 10 minutes max. I pull around the same weight maybe a little less. I also have a 05 PSD FX4. I am completly stock for now, but this week I am getting my exhaust and next week my SCT so we shall see how it does after that.
