HELP! Less than 48k & car started 2 stall & fumble while accelerating

Even tho my 2016 has less than 48k, I do drive it hard. I'm on 3rd set of brakes & 5th set of tires. Besides the fuel the dealership put in it, I've only put 91 octane or premium gas. 1.5 yrs ago, I started adding octane boost. Besides a cool air induction system, the car is bone stock.

1 week ago driving on freeway, the car started hesitating & I could feel little backfires. There isn't a CEL so I used my obd2 when I got home but it shows no problems. Ive read change coil packs & plugs but could they be bad already with less than 50k miles?Anybody have this at low mileage?
