Dinan has released their performance tuner for the BMW F8X series. It comprises of an electronic tuning upgrade which allows the new incarnations of the BMW M3 and BMW M4 to reach 516 horsepower and 489 lb-ft of torque with their tune added. The power increase is achieved by modifying the car’s software, allowing for a better air – fuel mixture and producing staggering results with a Dinan warranty, ensuring your engine runs smoothly without any worries about the added performance levels. This also means no internal components of the engine are touched, making the warranty claims even easier that way.

The DINANTRONICS™ Performance Tuner is a highly engineered and sophisticated piece of computer hardware and software that enhances engine performance, without negating or voiding your new car warranty coverage and without affecting long term reliability or the functionality of on-board diagnostic systems. It was also designed to be emissions legal in 50 states (E.O. Pending). The ultimate objective of developing this piece of technology was to provide the ability to control every signal entering and exiting the BMW factory Engine Control Unit. These items are unique to Dinan and together they embody the apex of performance engineering in a powerful, reliable, and warrantied package. – Dinan

The figures seen here are an impressive increase compared to factory output of 425 horsepower and 406 lb-ft of torque with all internal parts as standard! This is an increase of 91 horsepower and 83 lb-ft of torque as well. According to Dinan, the power delivery remains smooth and no particular issues are seen with using this system. We are interested to see what their next stages will bring us, as this done with a completely stock exhaust and intake system.
