MAN is part of the TRATON Group (the Volkswagen Truck & Bus division). The TGS, TGX and TGM are MAN's main truck series. MAN is a German truck and bus manufacturer, founded in 1758. Top diesels in long-haul tractors sit at the power ceiling, and Stage 2 requires hardware. Mid-generation truck models use standard OBD read/write. Truck diesels carry an extended set of maps for commercial load, with the focus on torque.

The professional logistics segment tunes for fuel consumption and pulling characteristics. The truck chip tuning community is an industry of its own, focused on long-haul routes. Top MAN units sit at the power ceiling of the European truck segment.
