Whenever you change the air metering device on your engine, you MUST recalibrate the tune. Because each model of sensor has its own unique air flow curve, the ECU needs to be reprogrammed to use and understand the signal properly. Our MAF software is unrivaled. Not only does our software take care of the intricate details associated with recalibrating the code for a new sensor type, we also optimize all other parameters to yield the best performance. With years of software development behind us, we have FLAWLESS tunes for your BMW. With software available for stock applications to high horsepower turbo applications, we have the solution for you that will blow your mind with its pristine drivability.
The M3 MAF is a nice upgrade for your peppy 4 cylinder. It offers a PEAK gain of 16 true HP at the wheels and a PEAK gain of 12 ft lbs at the wheels! Even more exciting is the large torque gain under the peak number, an impressive 17 ft lbs at 3400 RPM! Dyno sheets posted below.
The M5 and M6 MAF’s had a few bugs during the Gen II life span. While most people didn't have any issues, there were a select few that had drivability problems. We are always learning and Miller Performance and striving to better our products and service. With GEN III we have taken our knowledge and improved the drivability of our MAF conversions for all cars. The Gen III/M MAF is by far the best conversion out there for your M5 or M6. With our improved design, the GEN III/M offers unprecedented drivability as well as better performance than any of our previous MAF conversions.
The stock intake plenum has a smaller diameter entry than the MAF. Standard silicone reducers are to short to replace the stock boot causing headaches and ugly messes of hose clamps. Instead of trying to mate two hoses together, we have custom length reducers made that will replace your stock intake boot entirely. These boots not only offer the right length, but are much smoother and offer improved airflow compared to the accordion style factory boot. Remember, this isn't necessary, but it will make your install much cleaner looking and easier to finish.
