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

 

can you give some specifics on how to help this with some tuning?

 

You might try adjusting your PE Commanded Fuel Ramp in Rate and PE Commanded Fuel Step Size. I did this to mine and other things mentioned in the thread below, and the hestitation is gone and I still have all my TM...

And check out this thread, it gets good around page two.
