SMA intake problem/Help

[ACR H2]

Hey everyone,
I just installed the H2 AirAid Air Intake System from SMA, and i am having some problems.
The H2 seems to have lost some power. when i am on the gas, the H2 is having a hard time breathing. you can feel it chocking, then all of a sudden, it opens up and starts accelerating. When it opens up, it does feel faster. Like a turbo or something. Like there is a delay in power. It also wont down shift as much.

Has anyone had a similar problem? Does the H2 need time to relearn the new intake mod? Could it be a bad MAF? Everything looks good and tight, i am really baffled and not sure what to do.
The only thing I did wrong while installing the intake is that I started the car and forgot to hook up the MAF, that was only for 10 seconds, I then reconnected it and took the H2 out to test it. could that have caused it?
Thanks in advance.
