Your use case is going to be exceeding the engineering envelope of the car with far higher frequency than most other owners.

Chances are, unless you are a professional, you wont be able to use the extra power unless you are maxing out the car

I track multiple times a month and I would advise to never run JB4 on the track. The stock tune with 93 octane is all you need

I eventually got bored of map 0 so i went and got an m4 lol

+1. If you're actually tracking your car, all roads lead to an M car. And then an M car leads to a P car...
