7.3L Boost??

Just wondering for those who have gauges, i have a 01' PSD, 7.3L and was wondering what everyone else was seeing in boost? How many PSI and what upgrades do you have? Also what temps are you seeing in EGT's? I have a 1805 SC and S&B Intake, Straight piped.

What are you getting at idle and do you have your exhaust probe in the manifold or pipe?

Ill idle around 350 or less. I let it cool down until my egts get to 350 then shut it off. It will go lower but after a drive it takes a while. My probe is in my manifold. Where on the manifold do you have it?

Passenger side manifold, i can look straight in the wheel well and see it, abuot middle of the manifold i guess? and i think my probes not in far enough cause i've got almost 2 or 2 1/2 inches of the probe sticking out so im gonna adjust that and then see what happens.

Ok the placement makes a difference too. Mine is at the rear of the manifold which is hotter.
