I have a 2014 Chevy Silverado, 1500, 5.3, Flex Fuel, 117K miles.
Do you recommend installing a Plug-in OBD2 Module, such as the Full Force AFM Disabler? I read this may help prevent engine damage by preventing the engine from downshifting to 4 cylinders. There are several makers, which model would you recommend, if at all?
Thank you for all your great videos and wisdom, you have helped a lot. I am around your age and it's so nice to hear straight honest talk.

The only foolproof solution is to install the lifter hardware kit. The dongles cause more problems than they solve. With your mileage its probably not worth it. I would just baby it until it quits, and have a backup vehicle plan in the meantime. Avoid these engines going forward. They were doomed from the get go.(avoid the 6.2 as well)

Stopping ignition on 4 of the cylinders eventually creates havoc with your engine. The head gasket will be under strain, cylinder heads...

I asked him a question 4 years ago about V8s and the possibility of alternating which cylinders deactivate, to try to help with cylinder wear. That engine management system is stupid.
Plugging stuff into your OBDII port permanently isn't what the engineers intended it to be used for. It was meant for pulling codes, which takes maybe 10 minutes. I can't suggest any, because my truck is a V6. If you want to do the modification properly, buy a tuner. You can request a tune that makes the truck "forget" it has that feature. The tuner mates to the truck, though. If you sell the truck, either tell the buyer the tuner comes with the truck for a slightly higher premium, or you can restore the factory settings and "de-mate" it from the truck before you sell.
Good luck.
