I think the 15 pounds of boost is a indicator of the restriction of the exhaust mainly the cats and if you are running stock manifolds and the stock cai lower your boost gain hp I would have at least started with a Roto-fab or Cold air intake I have about the same mods but I did have the Roto-fab with my mods but left the stock exhaust got 534 hp at the wheels 537 torque and I am putting down 13Lbs of boost because of the lack of LT and hi flow cats my tuner is Frost performance and because the boost was that hi he took some tune out of it to make it safe but I will be putting my exhaust on in July with another tune and bigger injectors so I should see much better hp numbers and lower boost hopefully about 10-11psi.
