Default 21 psi on stock motor?

My AP is showing me hit 21 psi - tapers off, but is 21 to high for a peak? Safe? Is the AP accurate?

Oh yeah, car is 2009 wrx, TMIC, TBE, UP, CAI.

what kind of downpipe do you have? that is kinda high. if you go too high the car is gonna overboost and your gonna get a cel. my stage 2 08 has never been above 17 psi. give some more details. what map are you using?

It's the stock VF52 (coated) and I've got an Invidia catless DP. I'm running an etune from Clark Turner until I can get it down to P&L for a dyno job. I'm just hoping to get some second, third, etc. opinions.

Thanks for any advice you all might have!

21 psi on your vf52 should be okay with a proper tune. that's what i peak at too.
