So you may want to update to the most recent hptuner editor and then update the tune on the truck with the new editor tune.

You will know if this is the problem if your traction control light comes on real easy when driving on a round about or clover leaf free way entrance at just a hair over normal speed, but not fast enough for traction to be lost.

The computer will see a g meter and steering angle and your tire speed and t/c numbers out of whack enough to trigger the t/c (and light)
Doing an update did not resolve the issue with the 08 & 10 colorado cruise control after a tire size correction was made.
