Default Slight boost creep, not enough to hit fuel cut, should I be concerned?

I just put my ProSport boost gauge in the car and I was hitting around 17psi on my stage2 06 WRX. The Cobb stage 2 map is set for 15.2psi, variance is 0.7psi, and fuel cut is 17.9 psi.

I had a slightly tweaked version of the Cobb map that had adjusted waste gate duty cycles and a lowered fuel cut (we set it to 17.09 psi) and I was hitting fuel cut in 4th/5th gear with that map, so we put the unchanged Cobb stage 2 map back on and I haven't hit fuel cut since then.

I'm going to do a log soon to verify the gauge is accurate, but assuming it is, how concerned should I be about this? I don't drive the car like an idiot and rarely drive hard enough in 4th or 5th gear to hit 17psi. And it doesn't creep past 17-17.5, I had it up to 110mph in 4th and it didn't go any further. I'm planning on getting it protuned eventually, just wondering how I should handle this until then.

Do 05 Legacies have a TD04? That's wayyy high haha. I see people running TD04s at 18-19 psi on protunes or custom self-tuned maps, but Cobb Stage 2 is set for around 15.

Ah.

Okay then.

The Cobb Stage2 Legacy GT map calls for 16.5psi, so sounds like he has worse problems than me either way haha.

Pro(or any other)tune will not get rid of creep.

True, but there is no way he's getting creep with his car.

Sounds like the WGDC's where too aggressive on one of those Cobb maps, and you where spiking a bit. Get a protune.
