Default 2023 XLT 5.0 Cylinder Deactivation / Tuning

Hey guys,

I am about to OZ tune my 5.0. I like the idea of the fuel savings while cruising, but it seems very popular disable. Any evidence that this feature is causing any issues?

Other than some people with aftermarket exhaust don't like the sound when the deactivation kicks in there are no issues I have seen.

I have the OZ tune with deactivation still active and I can't tell when it kicks in.
