This is our tried and tested tune for an E46 M3. These tunes were designed on a Dynojet dyno and tested in the real world! We offer both MAF based and ALPHA-N tunes. Our ALPHA-N tune has an additional 15% increase in power over the MAF based tune. The ALPHA-N tune requires the MAF to be deleted, and the installation of a new Air Intake Temperature Sensor included in your purchase. Please select whether you would like a MAF based, ALPHA-N / Mafless, or a tune for a Supercharged S54. All tune packages come with an OBD to USB cable and software to read and write your DME/ECU.
