Comp cams whistle/whine sound?
So I have an 08 GT before the cams the engine mods I had were LT headers, an Airaid CAI, Moroso air/oil separator, MSD spark plugs, and MSD coil packs. The car has always run great with no issues and I never heard any strange noises after installing any of those parts. I recently installed Comp's Mutha Thumpr cams and their phaser limiter kit and refreshed the computer with a Bama tune. It runs just fine I followed the break in procedure and haven't pushed the car too hard yet. It just makes a whistle sound almost like a turbo after the engine hits 2000 rpms and higher. I have a stock throttle body and intake with the charge motion plates still installed. I keep hearing different things like its the throttle body, or the charge motion valves, or its just because more air is being sucked in. But not everyone says they have had this happen. Does anyone know anything about this?
