He's probably complaining about the "drone" that some CAIs make. Bill can get rid of that drone with a custom tune, or, he can just return the intake to the stock one as he's indicated by trading for it. Personally, I'd get a Gryphon and a custom tune.
There's a chance too, that he could be running lean with the intake, but this may not be an issue on his model year truck. Again, a custom tune would eliminate that possibility.
