Boost Leak?

I got my boost & pyro gauges installed the other day & Im wondering about my boost numbers.
It hits around 15psi under WOT, but under 3/4 throttle just accelerating briskly it shows maybe 5-7psi, but then once it peaks it drops back down to almost zero even though I am still on the gas.
Does this sound like I have a leak? What kind of boost should I be seeing?
S.

No, it sounds normal. Once the engine speed matches how far you have your foot in it, the governor reduces fueling and boost drops.
