well I got a little over 500 miles on the D/A so i figured time to romp a little bit. I noticed that it shifts awful early.... although that may be characteristic of a diesel. (noobie) the turbo spools up around 1800-2000 and whistles from there on out.... then around 2850-3000 it'll back off the power and shift real smooth. Kinda anti-climactic as far as the butt dyno goes. this sound right to you guys?

:confused:

yeah, sounds about right, the duramax backed off before the shift in mine until i put in the hypertech.

It may also take some time for your trucks trans to "learn" a bit. Shifting up and down will improve a bit after you make a few up and down shifts in different throttle positions
