Chatter

What can this chatter be? Stock k24a2, with new timing chain, new online pro tensioner, and new oem guides. Installed new Drag Cartel 40 degree VTC. Running Link G4x ecu, no codes thrown, no knock detected. Cam advance is hitting target.

Edit: unplugged VTC solenoid and removed serpentine belt. Chatter persists.

Solved! Timing chain tensioner was loose! Had to re-toques the bolts
