Confused about acceleration

So I'm big on acceleration and how a truck responds when the gas pedal is pressed. I drove a 2500 mega cab first to which I was not impressed at all with the acceleration. Felt sluggish. Had tons of power just didn't move fast. Today I drove a 3500 dually that was awesome. Much faster acceleration at all speeds. My question is why the difference between the two? Transmissions and/or rear ends? Both were brand new off the lot. All stock. Is the tranny and rear that different in a dually? Tested both with AC on and off. Any ideas?
Tks!

I would bet the 2500 had 3.42 gears and the dually had 4.10's. That's the difference you're feeling.

fast vs quick.
the slow mega will go faster.
the 3500 will get up to speed quicker.

I agree with this guy (all SRW's come with 3.42s now). Plus, the dually might have the Aisin transmission which will feel different.

i was under the impression the 2500s were stock with 3.73s. I know my 2011 has 3.73s, maybe it was an added option on mine?
