Having an issue with a major surge, was able to log torque management during the surging and it comes up as "drag"...
Never seen that one before, what is it, and how do you defeat it?
I can get around it after a little bit of driving, by giving it a decent downshift, then all seems to work normal and surge and the drag torque management are gone.
Starts around 44 seconds into the log.

I see it all the time, Its the rollout ratio of the tires front to rear and reported by the ABS module. I assume it has drag radials on the back and stockers up front?
Grab a factory set of rears and try it again and you will find it gone. The only solution I have found it to swap the front tires out to something that maintains the proper ratio.
Yup it sure does, it has the weld drag pack on it. Thanks for the tip!
