Will I regret change to 3.55s from 2.76s

the same ones who worry about having to run premium gas.

that whole $5 more per tank is a total deal killer!
Um.. more like a buck a gallon. $20-ish per tank. If you drive 1000-2000 a year that's one thing. But up that to 10000 miles or more a year and I'm no, I ain't buying premium.
