How much boost pressure are you tuned guys seeing through the rev range as far as the turbo maintaining a certain PSI? What about peak boost pressure?

I have personally seen on several tunes ecoboosts (SCT w/ 5 star custom tuning) 18 on full load (up from 13-15 stock). I don't know about the difference between the "rev range" but I would venture to guess it isn't much different unless under load in which case it increases faster with a higher max.

For a performance tune you will see spikes into the 20's. But boost will sit around 17-18 psi.

Across the rpm range you will see from 230kpa to 210kpa absolute pressure (since that is the value that is datalogged it is easier for me to remember).

Yes, most of them are around 17-18 at redline, with some spikes to 22 when it spools up.
