Best way to check for boost leak?

I sure feel that I should have more power than I do with my 7.3. I have gauges and can get to 18lbs when towing. I usually see around 10 when really getting on it, but it seems that the boost is later in RPMs than i expected. It also doesn't have the power id expect, especially with the superchips tuner set to hi.

Whats the best way to determine if i have a boost leak on a stock engine? Should i retorque the bands? Any idea what the proper torque is?

I have a superchips 1705 tuner on my 7.3 and could easily hit 23lbs of boost before it defueled.I had then same amount with my bullydog too.Sounds like something is wrong to me for sure,I would look around the boots and make sure there are no leaks around
the boots or up pipe.

I WOT'd last night and hit 23psi eventually, but its not instantaneous by any means.

I built a home made leak detector last night but did not have a chance to try it out. I did notice that the couplers BELOW the turbo (I guess the couplers that attach to the engine intake manifolds) are covered in greasy black crap. Id normally attribute this to a dirty oil engine, but up high I'm nervous that this is soot. Is this the tell tale sign of a leaking turbo runner?
