I attached a bravo gear ratio chart for anyone that may be interested in knowing the gear configuration for a particular gear ratio. For Bravo one users (Not XR) an alternative to your 1.5:1 ratio.

I lost no rpm or acceleration but picked up 2MPH on the top end. Probably shouldn't let out these secrets. Here you go:

That's great, but that's all ready available right in the latest service manuals, for all the ratio's.
