Here are my results from the weekend, for anyone wondering about JB+ on a 330i.
- 2020 330i xDrive.
- JB+ on default position.
- Cinturato P7 RFTs.
- Shell 93.
- Ambient temp 63F.
7.144s - 2.111s = 5.033s (last frame showing 0 on the speedometer to frame when it updates to "64")
Things I noticed after I got home: I left it in Comfort mode and my tires were over-inflated by 3 PSI... Didn't feel like traction was an issue, though.
