Chip tuning for DAF LF55 GR165 6.7L 220hp (162kW) 850Nm ECU
DAF LF55 (I) GR165 6.7L 220hp (162kW) 850Nm — commercial diesel engine of the commercial segment of the PACCAR (с 1996) group (Нидерланды, 1928). Stage 1 chip tuning raises power from 220 to 250 hp (+30 hp, +14%) and torque from 850 to 970 Nm (+120 Nm).
DAF is a Dutch truck manufacturer, founded in 1928. The XF, CF and LF are DAF's main series. DAF specialises in long-haul tractor units and medium-duty trucks. High-output diesels head the truck segment, and Stage 1 is especially felt in Nm. 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.
On high-output trucks, Stage 1 reduces fuel consumption under load. 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. High-output MAN units are long-haul tractors with solid headroom for Stage 1.
