Is my boost to low?

I noticed that i cant get my boost above 14 psi. Do not have any codes and does not smoke one bit. Seems to have lots of power and the usual turbo lag off the line. I hear the vgt doing the sweep from 15% to 85% when it idles. I get 13-14 mpg in the city and 18-21 on the highway most of the time, all hand calculated. How would i know if my turbo needs cleaned? If the truck is doing the vgt sweep that means it should be ok right?

14 is pretty low for a tuned 6.0

I would try installing an analog boost gauge that reads from the intake elbow. Way more accurate.

low to mid 20s is perfectly normal when stock, that's what I would prefer to see with stock headbolts.
