I use it after I re-enable the fuel trims or just want to reset them depending on if I fixed something mechanical or tuning wise. Just a simple thing to do to make the computer start learning the fuel trims again.
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.
