Nope, your gage is working properly. Your Bypass Valve is opening up and bleeding off the extra built pressure. You need to do the Boost Bypass Mod.

yeah, boost bypass, idk if you will see 16-17lbs tho, try 15....MAYBE 16...in FL with a 2.9 you will see 15-maybe 16 so...

Yeah it should build boost quicker, then hit almost 15 then drop back down to 12 near redline, wit the boost bypass mod, you will hold full boost all the way to redline, let me take a pic for you man, brb
