The BMW B58-powered lineup — including the M140i, M240i, 340i, and 440i — has redefined performance benchmarks in the straight-six turbocharged segment. With its 3.0-liter twin-scroll turbocharged inline-six, the B58 engine is renowned for its robust factory output, over-engineered internals, and massive untapped potential.
At Evo Performance, we’ve engineered a Stage 1 upgrade package that extracts the very best out of this platform while preserving the everyday drivability and factory reliability BMW is known for.
Whether you’re launching off the line or powering through long highway pulls, our Bootmod3 Stage 1 ECU calibration, paired with carefully selected supporting mods, transforms your B58 into a precision-tuned powerhouse.

IMPORTANT NOTES FOR SOUTH AFRICAN CLIENTS
95 RON fuel is fully supported with a catless downpipe.
We do not recommend custom tuning on 95 RON — BM3 OTS maps have proven to yield the same results.
Post-2021 models may require bench unlocking (contact us for compatibility).
TCU (ZF8) tuning optional at this stage but available for quicker shifts and torque management.

SOUTH AFRICAN CLIENTS – TUNING INSIGHT
We’ve conducted extensive testing with local fuel blends and found:
Bootmod3 Stage 2 OTS maps outperform or match most custom tunes when used with 98 RON and E30
No meaningful gains from custom-tuned files unless going full E50+ with supporting mods
Ethanol tuning must be accompanied by a proper ethanol content sensor (no guesswork)
Therefore, we do not recommend custom tunes at Stage 2 unless pursuing hybrid turbo or Stage 3+ goals.
