Which BMW M135 xDrive version do you own?

Compare the generation, year range, engine code and factory power, not the model name alone. These listed versions have 300 PS factory entries. Different outputs can use different turbochargers, control units and transmissions. Registration and software identification are checked before a calibration is agreed.

Open the exact engine record for the recorded ECU family, gearbox options and supporting hardware. Stage 2 values only apply to the specified configuration; unavailable estimates should not be borrowed from another engine. A newer software revision may also change the programming or unlock method.

For mobile enquiries, include the working postcode and parking arrangements. Physical upgrades and some ECU preparation require Slough workshop access. Output figures remain library estimates until supported by documented evidence for the exact setup.

Understand the hardware before choosing Stage 2

    I wanted to leave a genuine review, I got my car remapped on the 5th June 2026. Making the appointment was very easy, I didn’t have to wait too long for an appointment and had the option for someone to come to my house if needed. The remap was done within an hour or so. My light did come back on a week after the remap was done, but I was able to clear it with no issues and last weekend I took a 4 hour round trip to the beach and the light did not come back on when usually it does after about 1hr into a drive. The point of my long review is I highly recommend this company and I am very happy with the service provided.

    First time tuning my car. Didn’t know what to expect but it was amazing. They explained everything to me clearly, how it works etc and before you know it my car was ready. 10/10 polite service. Will be coming back in the future with serious motors, can tell these guys are professionals judging by tons of performance cars outside.

    Really five star service I’ve only got my car the day before I messaged on a Sunday just as an inquiry was more than Happy to take time of the day on a Sunday to fit me in last minute just want to think the whole team very professional and I absolutely love my car. I felt an instant power boost and explained everything to me and packages that I can definitely most likely in the future upgrade to will be definitely coming again.

    STX Tuning were absolutely brilliant. The service was super fast — same day turnaround — and they solved an issue with my car that a main dealer claimed would cost me thousands to fix. It turned out the expensive repair wasn’t even necessary, and STX handled it quickly and professionally. Honest, efficient, and highly recommended!
