I took delivery of my 75D S in December 2017. I had assumed my car had been uncorked at delivery...but you know what they say about assuming. Anyway - I was exploring some rando threads about the API and came across a post that mentioned that someone else had a car that hadn't been uncorked and proved it with the "perf_config" setting in the API to the service center. For the lulz I took a look at my own perf_config setting and noticed it wasn't "P1" as it should have been. After a call to my local service center a mobile tech came out and did the update; it's like a brand new car! The 0-60 is batshit rad. Code: curl -s --request GET \ --url https://owner-api.teslamotors.com/api/1/vehicles/your_vehicle_id/data_request/vehicle_config \ --header 'authorization: Bearer your_bearer_token' \ | jq -r .response.perf_config If you're uncorked this will result in P1 (if you're in a 75D at least) So thank you to everyone who posts here. You provide valuable information and I'd still be corked if it wasn't for everyone in the Tesla community!
