New Boost Gauge. Leak or normal

I’ve seen a lot of different readings from different people and gauges so I’m hoping somebody on here has a similar setup and can tell me if I might have a leak or if I’m normal.

Eurojet electronic boost gauge, vent pod: Hitting 15 psi and holding at WOT. Did spike at 17 once.
3" TBE, intake, 42 DD stealth catch can, noise pipe delete with OEM tube, revision “D” dv, new plugs and “F” coil packs, tapped the boost with the 42 DD boost tap to the supplied Eurojet filter then to the electronic sender. APR Stage 2. FSI motor.

No HPFP. Cam follower changed 6200 miles ago.

Anybody have a similar setup for comparison?
