Has anyone heard of or experienced any deterioration or damage to a post 2004 496 with the Pro-Charger upgrade? 3lb or 5lb?

Procharger only offers a kit for the 01-04 496 and the only thing available for the 05- is whipple, this is because the change of the ecm. What is the serial number and we can check your motor. I have had nothing but very positive feedback with the 01-04 kits I've sold. There is can be some clearance issues with the seat and the stringer as well.

I'm not as concerned with the ECM as I am with the piston change that happened in 04.
