There is two different boost measurements taken by the AP. There is absolute PSI which is what the DME uses for boost targets and then there is "boost" which is basically just for display purposes and is dispalyed in PSIg. Which is where your confusion is coming from. Compare boost mean abs and req boost abs NOT boost(psi).

PSIg + atmospheric = absolute PSI

As far as your log is concerned it looks pretty good aside from the boost oscillations you're having down low.
