Supercharger vs. gears. Either? Or? Both???

[Spenser]

I understand that the gears are a lot of "bang for the buck", however, my concern would be how will they actually affect my top end, I mean, has anyone done the math regarding the difference in rpm at say 80 mph? I believe that currently I have a 4.10 gear set and would be changing to the 4.56 set. Now if the supercharger can provide the added "zing" under normal driving conditions then all the better. I've added the exhaust, cold air box, headers, and programing, and they made a noticable difference, (however, I've been told that with the addition of the supercharger, the headers need to go bye bye) I'm just wanting to add a little more "zing" under normal driving conditions, and a hell of a lot more when I really need, or want it. Thanks for the response.
