2019 5.0 backfire
I have a 2019 f150 with the 5.0 coyote. What's weird is when I accelerate in sport mode it backfires. If I get on it hard, I have no issues, but if I'm only on it halfway or so, it's horrible. I read the thread about the long stroke and short stroke when you let off the accelerator, but that's not my issue. I have yet to take it to the dealer as it only has 15,000 miles on it. Lord knows I'll be told it's normal. Any ideas? thanks

Is it a backfire or an exhaust crackle? A backfire sounds like a 12 ga shotgun blast. 5.0s do the exhaust crackle quite a but. Mustangs with aftermarket exhaust are bad about it, I hate the way they sound.
