Mack Trucks MP7 (I (2005+)) MP7-355E (US04) 10.8 360hp (265kW) 1843Nm — commercial diesel engine of the commercial segment of the Volvo Group (Mack Trucks) group (США, 1900). Stage 1 chip tuning raises power from 360 to 415 hp (+55 hp, +15%) and torque from 1843 to 2148 Nm (+305 Nm). Diesel engines built in 2005 — the era of classic Common Rail without strong encryption.
Mack has been part of the Volvo Group since 2000. Mack Trucks is an American truck manufacturer, founded in 1900. The Mack Bulldog is the brand's iconic emblem. The factory calibration is conservative, leaving headroom for Stage 1 while preserving engine life. Top diesels in long-haul tractors sit at the power ceiling, and Stage 2 requires hardware. On older truck diesels, Stage 1 goes in over OBD with no complications.
The truck chip tuning community is an industry of its own, focused on long-haul routes. The professional logistics segment tunes for fuel consumption and pulling characteristics. Top MAN units sit at the power ceiling of the European truck segment.
