Track mode not shifting correctly loss power?????

Hey guys so I’m honestly realizing that it’s something probably wrong with my car or I’m over thinking it
2 things

2021 Dodge CHARGER widebody hellcat only 15k miles on it been doing it since it had only 6 miles on it

1. Dyno pages I’ll down shift to third gear even 2nd gear while driving and smash the peddle to go and my car will shift hard on track mode (which is normal) but every now and then the car would shift so hard it jerks the car back or studder the car (as if the car can’t shift correctly) all in “auto drive” that is NOT normal I’ve had two different dealerships look at it and nothing found it’s been doing it since I bought it brand new

2. Dyno pages will show my horsepower only get up to 660-680 max and hover around the 570-600 area on the dyno that comes in the car i know it doesn’t show Whp and even if it did thats not accurate and it feels slower than usual unless I’m used to it now

Any ideas or suggestions???
I came from a scatpack and my scat pack never did anything like that
