After weeks of extensive research and testing on our Audi RS4 Avant 450hp (2018) development vehicle we are happy to release custom engine software upgrades for the 2.9 TFSI EA839 engines with Bosch MG1 engine control unit (ECU)!
Our development program did included hours of dyno testing, street measurements and analyzing data. With these enourmes amount of data we created final calibrations that are fine tuned for several fuel qualities and octane rates. As always, our goal is to achieve the perfect balance between maximum performance, drivability and durability!
Significant performance gains up to 530 hp (+80hp) and 750 Nm (150Nm) are achieved on RON98 fuel while maintining safety functions to protect your engine in extreme conditions and scenarios!
