Enjoy substantial power and performance gains thanks to Ecotune's expert calibrations for BMW 3.0L petrol engines. Whether you are running a B58 or S55 platform, this software provides elite increases in power and torque hitting hard every time. Strictly developed for 99 RON fuel, it includes enhanced engine cooling and improved throttle response for professional-grade results.

Optimized for hybrid turbochargers from Garrett or TTE. High-flow intakes and intercoolers from Forge, Eventuri, Racingline, or do88 are strictly required.
Mandatory large-bore downpipes from Scorpion or Milltek.
Upgraded fueling components required for sustained Stage 3 targets. Flex Fuel ethanol support available where hardware allows.

Installation Requirements: Your vehicle is booked for Ecotune Stage 3 tuning. Before any calibration work begins, a full pre-tune inspection must be carried out. This inspection is essential for Safety & Reliability, Correct Hardware Verification, Ensuring Accurate Calibration, and Preventing Avoidable Issues. We check: Turbocharger, Cold air intake system, Turbo inlet pipe, Low-pressure fuel pump (LPFP), High-pressure fuel pump (HPFP), Upgraded injectors, Intercooler, downpipe, exhaust components, and all performance-related modifications. All software must be reviewed and signed off by the Ecotune Calibration Team. The vehicle will not be released in a tuned state until this approval process is completed.
