Any ratio change means you either have to change your plastic gear on the VSS or change your VSS constant in the PROM (if you prom tune)

Theirs a good little chart in the tech articles off of the TGO main site, Shows what colored gears you need to match up with the rear end gearing. I believe it also gives the part #s for them too.
