First off.. What is the size of the stock Supercharger pulley?
As for the smaller pulley's. If it's a regular press fit pulley like all Eaton superchargers use. You can use the Pulley's designed for the M90 Supercharger. The shaft is the same size.. The only problem is if the snout is able to accept smaller pulley's.
From what i've read.. The ECU is already dumping boost because it's designed to at a certian point. Without a cracked ECU.. The smaller pulley will only add Low-Mid Range Torque.
If i go ahead and purchase a used 04 Redline. I'll have a writeup about how to install a smaller pulley in a week's time.
