I'll say 4-2-1 cuz it gives you more low end power while 4-1 give you high end power.

What exactly does that mean? Low-end meaning lower RPM and 0-60 and high-end meaning higher RPM and top speed? In a 1/4 mile run my RPM are only below 4000 for like the first 2 seconds (if that).

yeah, for drag racing, 4-1 is better, but for daily driving, 4-2-1 is a little better.
