Using 4wd

[5.3L11z71]

I notice when I'm in 4hi and I step on the gas the truck has no go!!! Does this have to do with the torque management?? I'm still new to all this. I plan on getting Nelson tune in couple of weeks hopefully to solve this problem if that's the reason. Any help would be appreciated. Thanks, Eric

You have significant parasitic loss when running in 4wd. You need to remember that when you run in 2wd you only need to turn 2 tires vs 4.

Its a combination of parasitic loss and traction control.

I easily lose half a second in the 1/4 when in 4x4.
