Diminished Driver Side Exhaust Output

[sixpax]

I installed an ARK Grip CBE, Berk HFCs and a K&N Typhoon this weekend. Took a heck of alot longer than I anticipated, but I am pretty slow.

After everything was checked for tightness, all the parts back on and taken of jack stands, I started it for the first time praying for no CEL light.

So far so good...no CEL. Let it idle for about 5 minutes and took it for a brief spin around the block, and when I got back I left it running and exited the car to enjoy the rumble sound of idle. I noticed that one side (driver's) seems to not be expelling as much air as the passenger side, which is blowing strong.

I treated the MAF sensors like they were the Hope diamonds during the whole process, so I doubt I got them dirty or anything.

I double checked the hose connections to CAI to make sure everything was vented correctly, at least according to the shoddy directions.

Car seems to run OK, I don't really want to get on it yet so not sure of any noticeable gains beyond it sounds meaner.

Is this just because the brain has to much to relearn at this time, and will improve with time ? Or is it something I should be concerned about ?
