Boost leak? Not sure?

I have APR software, borla exhaust, and piggie pipes. I am boosting to 15 and holding at 14, do i have a leak? I think i must, seeing in other posts people reporting 17 spike and 15 hold. Please advise, thank you.

What octane is your software for? And building/buying a pressure tester is a must for these cars.

93 octane.

Are you having any running issues, does the car pull hard? Never a bad idea to pressure test every so often. I usually do it at least twice a month.

No running issues at this moment, no cel, no nothing. Pulls hard, and feels good to me. I will have it pressure tested this month, just thought i would ask.

sounds like a leak because i know apr i believe is hold 15 spike to 17 then back down to 15. im not sure maybe someone can chime in because i have giac and i know im holding 16 spike to 18 then back down to 16.
