Rapping, Ticking, Knocking

[Charger68]

I set up a warranty appointment with the local Ford dealer for an under hood noise. I have a 2025 GT, 6 speed, Active Exhaust, with 1900 miles that exhibits a clatter, rapping, ticking of sorts during, but mostly when I let off the accelerator. It isn't constant and improves when the car warms. I've speculated lifters, injectors, and even Active Exhaust. It might even be normal, but my former 2025 GT Automatic, Active Exhaust, didn't have it. Does your 6 speed exhibit this characteristic?

Yes, I have the same setup but a 2024, around the 2000-2100 rpm range there is always a mechanical rattle/tapping, it sounds like noisy tappets to me, but I'm no mechanic.

That's the DI fuel pump starting to engage.

Thanks. Did I just not notice it on the Automatic car? Or is the pump making excessive noise maybe?

Lots of people report hearing it. Look up "2k rattle".

I've also been told by the dealer that's the DI injector (driven off the right side cam) and not to worry. Fine, but if you would not like to hear it is there a way to eliminate or quiet it down?

I've had my horse checked for this sound. Techs said its normal PCV sounds. Here is the write up. Engine noises aren't the issue,,I just want to know exactly what is causing it and if it's the pcv why it cant be remedied.
