Would it be worthwhile for me to change my current gearing (2.73) to 3.23 or 3.4x ? I'm thinking theres a few tenths to be had in doing so, unsure about the mph. I've heard some people say that with a TC gears really dont matter?

 

You would see probably 3 tenths or so from a swap to 3.23s or 3.42s. .4 from 3.73s. It's possible you could gain more.

If you get a high enough stall, you won't benefit as much from gears, you'll just be screaming anyways.

If it were me, I'd at least go to 3.23/3.42 gears. Cause there will be times when you can't always use your tc.
