Any Chrysler Techs out there?

Agreed with Killer 6. Fuel quality can be terrible, especially this time of year.....my area is known for it.
I've seen symptoms like this with customers vehicles in the past.
In a case like this, I have recommended trying an octane booster with a fresh tank of fuel.
Every problem has to have a starting point and that's about the easiest and cheapest thing to try.
If you choose to try that, make sure you get a booster, not a fuel injector cleaner, big difference.
Secondary ignition has been replaced, so you can pretty well rule that out.
Possible fuel injector problem at higher rpm, watch fi data and test resistance of each injector if you can.
Otherwise, if you have the ability with the scanner you have, monitor each individual cylinder for misfire and see if it is just one particular cylinder, or a random misfire. Wastegate solenoid could have effect, rule it out first.
