2002 7.3 Ford Boost Pressure?
We have a F-250 4X4 with a 7.3 Diesel and 6 Speed Manual. I use a scan gauge to monitor engine data. We bought the truck new and it seems to be in very good shape but I am wondering where I can find...

I was thinking that if I am pulling a grade at a steady 1750 RPM and 100% throttle the boost would be near maximum.
Thought that because that because peak torque 1750 RPM.
I am not sure I ever see 17 PSIG. I will check the boots and clamps.
Should my waste gate be in good shape at 90K miles with almost no trips of less than 50 miles and very little stop and go miles.
Hi. I used to have the same truck and as I recall you won't see 17 psi at 1750 rpm. Drop a gear and put the throttle on the floor however and you should see 17-18 psi.
If boost is low check hoses as people have suggested. Also investigate for signs of exhaust gas leakage where the up-pipes coming off the exhaust manifolds enter into the bottom of the exhaust turbine housing (black streaks on the pipes, etc). 7.3s are known to leak there, which causes less exhaust gas entering the turbine, which can lead to low boost pressure.
