Mosselman iTronic, BMW G-Series M2/M3/M4 S58
The iTronic is an advanced engine controller that works simultaneously with the original ECU and is highly recommended on new and young BMW models that still have the factory warranty. It is designed as an external module (tuning box) that can be installed and removed by the end-user, minimizing problems with the factory warranty.
The iTronic will take your BMW G87 M2 to approximately 600 hp and 750 Nm on premium fuel (98 Oct EU/ 93 Oct USA), which is highly recommended.
