BMW S58 Tuning – Since mid-2020, Bosch has implemented significant security enhancements across their ECU platforms. As a result, extracting additional power from BMW vehicles has become both expensive and complicated, often voiding the warranty for BMW owners.
However, our BMW S58 Tuning solution for the M2, M3, and M4 models offers a straightforward and removable alternative. This Stage 1 Tuning Box is not an outsourced product; it is entirely designed, developed, and manufactured in-house at our Suffolk headquarters. With proprietary code, we maintain complete ownership and control over the product. Our BMW S58 tuning box solution safely delivers over 100 BHP over stock and is covered by warranty.
