Review on Qzucar Active Fuel Management (AFM)/Dynamic Fuel Management (DFM) Disabler for V6/V8 GM Vehicles - RA003 by Richard Bowens

My husband ordered this for his 2019 Cadillac Escalade. We often use this SUV to tow our boat and wanted it to always run in V8 mode. It's so easy to use, just stick it under your dash and it works great. Is it worth it? I have read several articles on the internet stating that active fuel management systems are bad for your engine. If the $100 price tag for this blocker prevents costly repairs, then yes, it's worth it.
