hey guys im wondering what affects the airflow mass reading besides the obvious stuff like mods, tune, temperature etc.

i have a couple data logs from before i installed my front mount and my airflow mass was about 21.5 at 5000 rpms maxing out at 22.2 ish.

now with the big front mount intercooler i just got a reading of 20.5 @ 5000 rpms. i know there is a pressure drop associated with bigger intercoolers. im wondering if the intercooler would also affect the airfow mass. and what else could be affecting it?
