Just curious, I've drove a few 04' impalas at work and for some reason they seem a lil more quicker than the average stock 3.8

Did they have a more finer tune from the factory or did they have a fewer more lower gears?

I have a LS and GS, and those impalas definatey move quicker and have a more torquey pick up then a stock LS regal.

Anybody know y these lmpalas seem a lil qicker out the box?
