Will I regret change to 3.55s from 2.76s

I've been really paying attention to the tach this week and you are correct. Even under what I consider pretty decent acceleration, I almost never even hit 2500 rpm. I drug the rear out after work today so I can start hacking. I never realized how much I've been holding it back with the 2.76s until reading all of these responses. I'm pretty excited now to see what I've apparently been missing.
Hp percentage of torque is less than half at 2500 rpms and under and by 1313 rpm is a quarter. So if making around 300 lbs-ft your only seeing 150 hp or less definitely not getting into the power.
