How does remote tuning work for the BMW X3M?
You send your vehicle details, mod list, fuel, and goals. We review the setup, build a base file, review logs, and revise the calibration until the package is dialed in for the BMW X3M.
What fuel should I run on a tuned BMW X3M?
Use the exact fuel the calibration is built for. Many S58 setups are tuned on 93 octane or an ethanol blend like E30, but the best option depends on the hardware, climate, and fueling support on your car.
