I recently installed a brand new 65MM Eurocharged SC pulley and a Needswings Pulley Saver Kit.

I've noticed after a week im getting a whistling sound whenever i accelerate and push down on the gas pedal. Different whistle sound from the supercharger. Could it be a bad idler pulley?

The only thing I had done was that, tune, new plugs and wires installed and they took off part of my intake.

I was thinking a intake leak somewhere, but I have contacted Rob on the issue. Just seeing what your thoughts were or if someone has experienced something like this?

Thanks.
