E46 Tunes

Shop Poverty Built BMW E46 tuning by the engine-management system that is actually installed. Supported paths include MS42 for many M52TU 323i/328i applications, MS43 for many M54 325i/330i applications, MS45.1 for later 325i/330i/ZHP cars, and separate M3/S54 options.

Do not order from the model year or badge alone. Verify the DME first, especially on swapped, converted, or replacement-module cars. For naturally aspirated Poverty Built tunes, the stage describes the behavior you want; the installed hardware is selected separately so the calibration matches the car.
