BMS DCI question

I installed the DCI and i thought it was a snap until i tried to fit the one by the firewall. Not so easy took me a few tries since i was by myself.
Anyway, i can hear the whoosh sound which is normal but as soon as i step on the gas about 2k it is super noticeable. I am thinking ok normal but at 2500-3500 the car seems to fall on its face. almost if there is to much air and it canít get out of its own way.
Is that normal?
Could i have knocked something loose that I donít know about?
Even if the intake was not air tight it still should not be falling on its face should it?
Does the ECU take awhile to adjust?
