07 Sierra 2500 HD hesitation

My dad just bought a 07 Sierra 2500 HD with the 6.0L and 6L80 transmission. It seems to have a hesitation when you step on the gas to go. I deleted the torque management with HP tuners thinking that would take care of it but it seems as if it actually made it worse. Does anyone have and ideas for a solution. It is completely stock except for the torque management deletion.

most of that has to do with the electronic throttle body, but it can be helped with some tuning
