Swiss cheese the air box

So is there someone out there that has done the swiss cheese to the air box and has gotten good results? Should I just cover up the holes with duct tape and except that I screwed up?

You are not alone. I put three in each side and then found out that I had a terrible flat spot as well. I didn't have time to fool with it, so I dropped mine off at the dealer too. I should have it back in a few more days, so I'll let you know what I find out. Also, the service guy mentioned advancing the timing a tooth. ??? I guess what I'm trying to say is that I just really don't know a freakin' thing except that I did it too.

There have been many succcesful attempts at modifying the air box, and all of them have been to cut 1 1/2 inch holes in the right side of the box and insert filtered vents(which dampen the flow) but still allowing increased airflow. (Moose makes the inserts).

There having been many succcesful attempts is a plus. I'm still waiting on the results from the shop.
