I did not change oil weight on my car until after I added a performance tune to my 5.0 and figured my engine warranty was gone at that point (completely different topic on if warranty is void or not from tune topic for another day) anyway after tune I switched oil weight. But if I had the "BBQ Ignighter tick" I would stick with the 5w20.
It would be more consolation if I weren't so alone in seeking resolution for this. I left the car stock because long ago I modded my old car to high heaven and when the oil pump failed and took out the engine It cost me dearly. I haven't driven or ridden in a car with a tune or mods, and while I agree this thing stock isn't quite quick enough (old car was 390 hp and 2850 pounds, this is 420 hp and 3650 pounds), I am certainly glad I kept the warranty. When my warranty expires, then I may tune the car, do my best to ignore the ticking, and put some redline 5w30 in there.

I had seen a post someone with an oil pressure gauge said the oil pressure with 5w30 was all within spec, and again, with no mechanical differences between the track pack engine and the regular GT engine, there's no reason to see it being problematic. The ambient temperatures in California this time of year are also really hot, so everything will be running hotter from that.
If Ford's decision is that this is normal:

and they will help no more, I may run 5w30, but for the moment I need my warranty.
I listened to the video and I think the engine sounds great! Maybe my ears just can't detect any strange noises or I just don't know what I'm listening for. One question though,why did that brand new Mustang need a new engine?
The speakers you use make a big difference in whether you can hear the ticking. Try listening to it on your phone, anything with less bass usually makes it stick out more.
This is the old engine:

Same problem. Started running rougher and rougher. Finally found a dealership that would look into it, they found a bunch of damage/failed specs and replaced the longblock.
I know a lot of these cars get the bbq tick, but this is not normal. I ask every 5.0 owner I see and have never met someone with the problem. You can imagine after 9 months of research and trying to find a dealer to look into it, which dealer tried to blow me off at first, that I felt elated. Then within 300 miles the new engine started making the same noises minus the snapping at idle. When I got the first oil change it came back just like the old engine. Maybe the damage was incidental, I don't know. Maybe running 5w20 oil in 110 degree summers is stressing.
I have seen plenty of people posting their track packs get the problem, and just as many saying that the switch to synthetic oil from the blend causes it, but my experience on the latter suggests no relation. I tried redline 5w20 on the old engine, and the problem occurred much less, and went away maybe 100 miles sooner, but it didn't go away.
The old engine this would stop at around 850-900 miles after the oil change. New engine's still doing it at 1500 miles on the oil, just not enough that I can demonstrate it. The engine has 3000 miles on it. I changed the oil at 1500 as per the advice of the service adviser at my dealership. Popular mechanics recommends changing the oil at something like 20 miles on a new engine; changing the oil isn't bad for your car, so this is baffling.
