Default how much boost one the street?

if a turbo system is set up to run 15psi of boost, how much boost is it putting out while street driving (550-1600 rpm)?

On your performance oriented gasoline setups, you will not use your turbo at all unless you are pushing your car hard.... at that point, you will start building boost, etc. This is very different than the turbo diesel tractor trailers you pass on the highway... you can hear their turbos whistling for minutes anytime they're climbing a big hill, etc. Again, two totally different setups.

You got that right!! My Duramax runs at 5psi all day (if not more) at 75mph on the hwy. But I can still get 20mpg!! My AFR at cruise is probably 30:1 or leaner
