This is just because of your stock fuel dampeners and larger injector combination. 08+ they changed the supply and return fuel system. IA sells a kit that reverts back to the 04-07 fuel supply and return system. With tuning, this "hesitation" goes away. I've heard that the FIC 1000's or ID 1000's tune out better then the DW injectors though. My hesitation is gone but I also run e85 on the stock fuel dampeners. The code is not related to this hesitation.
