I had my intake manifold and throttle body ported by Peakspeed. After bolting it back up I noticed the gains. I also noticed an audible whirling type of a noise under throttle in the 2200-3200 range. Then I realized it actually sounds like a vacuum leak. I had a true CAI fender pull on the car prior to the porting and custom tune and still have the same set up after the porting. Is this normal? Car "feels" right. Anything I should check?

That bad a vac leak you think it would throw a code. And not run so well.
Id spray a little starting fluid around and see if it changes rpm. If it does, theres your leak. Or do the smoke testing for a leak.
