Get those active cylinders shut off! Lots of different brands do it but only a couple actually do what is needed. I am not in that world to know which one to suggest.

👆🏻 Automatic fuel management delete chip. It plugs into the OBD-II plug. They have cam problems on the cylinders that turn off. I have had multiple. Current 5.3L Tahoe has neatly 400k. On it’s second motor.

They had issues with them. Seems crazy to need to disable factory settings to make them last longer. Seems that is the way it is though.

The trans went out on my son's 2017 Sierra. Two catastrophic fails in one family.
