You already have a 4.10 that is about the closest you can get.

Chip is great, MarkD is what I use in mine. Flywheels is next, suspension is also a good idea. I have a 3.73 LSD and love it. I get about 30mpg on the highway and its still plenty fast enough to surprise people on track.

well i get around 35-40 on the highway still with my 4. but how much hp's gains would u expect with a markD chip? Its kinda pricey but if its worth the gain then ill buy it.

You may or may not have a Limited Slip from the factory, as it was an option.

MarkD is worth it's weight in gold. There's a group buy going on right now in the GB forum.

Get a 3.73 or 3.64 diff. Ebay chip works.

I got my MarkD chip on here for $175. If you keep an eye out you can get good deals. I got my LSD from a local forum as well.
