A few days after i installed a LS6 intake (removed AIR and EGR), i've noticed a fluttering/tapping sound when I accelerate. It's a soft sound, and it doesn't get louder the faster i go. Anyone have any ideas what this could be? Is it related to the intake install?

If you left off the foam under the intake it could just be your hearing more of the valvetrain noise. I noticed it with my FAST intake install and I did not install the foam.

Almost sounds like a vaccum problem. Is it driving ok? If it seems to bog a little make sure your bolts are at 89 inch lbs

it seems to drive fine. If it was a vacuum leak, would it throw a SES light?
