Make sure your connections are all the way in.
So far no problems. Works as advertised. Pulling the connection out is a bit harder than the videos show. Be patient and make sure you hear the connections click when installing.

No more 4-cylinder mode. No more auto-start and stop.
15 minutes of work eliminates that pesky Auto Start Stop and Dynamic Fuel Management. No more 4 cylinder mode. No more worrying that 4 cylinder mode might damage my engine. No more engine turning off at every Stop sign.

Worth every penny!
So grateful for this product! Can finally use the full potential of my 5.3 V8 all the time. The auto off/on disabler is super convenient as well.

Works great on my 21 Escalade
Bought this for my 21 Escalade. Start stop function is now gone and the car seems to run a lot better. No noticeable change in gas mileage after a 300 mile trip with both city and hwy driveing. A must have !
