About the BMW 3.0 turbo petrol (N54, N55 and B58: 335i, 340i, 535i, 540i, M140i, M240i, X5 40i)
BMW's six-cylinder turbo petrols, the N54 (2006–2013, twin turbo), N55 (2009–2017, single twin-scroll turbo) and B58 (2015 onwards), power the 1, 2, 3, 4, 5, 6 and 7 Series, X3, X4, X5, X6 and Z4 from 306 to 387 hp and are famous for their response to software.
How a Stage 1 remap works on the BMW 3 Series GT F34 LCI 340i Performance Package 360hp
Stage 1 recalibrates boost, ignition, fuelling and torque maps. The gain spreads across the whole rev range and is very clear in the mid-range. The automatic gearbox torque capacity is respected; knock-sensor data and fuel quality bound the calibration.
Pre-remap checklist
- High-pressure fuel pump and injectors (a known issue on the N54 / N55).
- Ignition coils and spark plugs.
- Turbo wastegate play and boost leaks.
- Oil consumption, PCV and cooling system (water pump, thermostat).
This section is based on Prime Chiptuning workshop experience; the power and torque figures come from the catalogue measurement above.
