Boost pressure

[JE_6.4]

What are the sort of boost pressures seen on stock turbos? Either standard or a supposed 80hp h&s tow tune. The reason I ask is I have a feeling I have a boost leak but I can't track it down and can't hear it. It's still pulling well but I noticed it smoked more than usual today, only had a u-scan on me so ran a log on my way home and wanted something to compare numbers against.

I Run a 210 TP tune Spa<tan. Have pulled a major mountain with 40 lbs. of boost, at 23K lbs. gross, and no heat at 90 degrees ambient Temp. More info, 65 MPH, 1725 RPM's. More Info is needed???? Boost controls, and is controlled by many things> We all want to help, but need INFO!

Here is the log from the U-scan.

75.3hg is around 22psi if I'm right as the map always sees 30hg when idling. Frame rate on the logs on that thing is awful but I don't have a monitor as yet to check it against anything.
This is locked in 5th, up a slight incline, ambient temps are 82 today. Bed full of stuff so guessing around 9000lbs. 3.73 on 35s

I run S partan tuning and I tow heavy and that's the only time I see big boost number's. If I fully loaded and accelerating moderatly, 40-50% throttle I can get close to 40 psi and if I really gata move 45-50 which is close to the max a stock turbo setup can push.

Over all the lower the boost and the more air being delivered the better, high boost is only a sign of restriction to the air be delivered and that's where bigger, better turbo's come in, tow twin's.....
