Yup, just set the enable to disable and that's it. Nothing else to do but flash the tune to the truck and you are on your way.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
thanks, but I'm a little too late as my engine now has a collapsed lifter
