It's called Torque Management. It makes the transmission last longer by reducing your power output on take off.
Of course your diesel took off faster. Diesels are made to get seemingly unmoveable objects moving.

Get a mail order tune or go to a dyno shop and get a custom tune. Don't know what you paid for superchips, but you probably could have gotten a mail order tune and actually made a difference.

YUP, I agree, it has a lot to do with TM.
I removed all of it from my Engine and Transmission. Big difference
