Default DAM dropped from 1 to .625?

I'm sorry if this has been asked before

04 STi
APS Front mount Intercooler
COBB cold air intake
3" Apexi Turbo back exhaust

Took the car out for a cruise and everything was fine, DAM stayed at 1 the whole time. Went to do a hard pull and then afterwards the DAM dropped to .625.

Is this something to be concerned about? I'm guessing it dropped because of the pull because otherwise the car has never acted up

If the dam drops during a pull like that it means the car is not happy,are you tuned?we're you monitoring knock during the pull or just dam?
