Default Intake leak?

After I got my car tuned about a month ago, I've developed what I think is an intake leak. Right as the throttle is cracked, you can hear a whistling. It seems to come from the front driver side of the intake or throttle body. When I installed headers and removed the EGR, I plugged it with a freeze plug, so that was the first thing I checked. I put a bunch of water on it and when I cracked the throttle it didn't seem to bubble or anything, so I don't think that's the problem. I also don't see any any holes in the rubber sleeve connecting the air lid/MAF/TB.

Anyone else have any ideas of what it could be or how to test it?

Take a propane tourch and turn on the gas,(no flame) start up the car and let the propane run around the intake and throtle body if the rpm's climb on there own you found your vac leak.
