K i just some pulls with my ap and at idle it says my boost pressure is 6.45 psi? and absolute is the same. Here's a quick pull i did.
It's with the Cobb Ams stage 2 map, does everything look good?( look thru cells 1-35 for the first pull)

 

Looks like you're hitting about 25 psi relative (subtract 14.5 from absolute to get the correct relative, assuming you are near sea level). You are getting slight knock up top. If you consistenly get knock at 5500 rpms and up, I would try to drop timing in those areas 1 degree to see if it goes away. The logger speed is also kind of slow. If you log fewer items (drop LTFT, TPS voltage, ECT, intake temp, boost pressure (since it's same as absolute)) that might give you better resolution.
