The electric supercharger that are sold on e-bay should help your low end.

The FI will be more expensive, for sure, but your highway mpg won't suffer that much if well tuned and balanced for road use.
The 4.77 drive is also intended for twisty roads\track\autoX use, the needs of a car used on a track are different than the needs of a "tuned" road going car.
I would say turbo and i have a shorter final gear
Especially if you like straight, off the line pulls the turbo will be the best choice. The final gear really only shows up during a twisty circuit!

Yep but the use for the final gear is still different. Shortening gears is not always a good solution

am I detecting sarcasm in that statement?
no, seriously I've never heard anyone say those electric turbochargers even work.

Give the guy a break... Only way is turbo, or Go S/C, which will keep nearly the same power curve as stock. Only difference, there's more power involved
