    03 Hd

    I recently bought a 03' HD and noticed that it had a rattling noise in the engine. I thought it sounded like it was the idler pulley,but after talking to the previous owner he said that it might have to do with the fact that he changed the lower pulley from stock to 12lb.Has any one had the same problem.I would like too know what it is before I take it in.

    welcome aboard...

    does it have a tune, does it have a chip or a tuning device like xcal II or predator that was used to flash a tune on the PCM....that rattling noise under heavy mod to heavy throttle is detonation...you really need a tune to run 12lbs of boost.

    If you got detonation....dont get into the throttle or bad things will occur, you dont want to become a member of the Vented Block club with your new ride.

    It has a Diablo preditor tune on it that was tuned by Johnny Lightning.The pulley was a lower #6.
