Wettstetten-based tuner MTM has developed a program for the 4.2 TDI V8 engine seen in Audi’s A8, Q7 and the Volkswagen Touareg.
Developing an impressive 258 kW (350 hp) and 800 Nm (591 lb/ft) in standard form, MTM can fit its V-Cantronic – to the A8 only, which disables the car’s speed limiter, meaning a new top speed of 282 km/h (175 mph). That will set you back € 1,400.
For € 1,800, MTM will remap your existing engine management system, resulting in 306 kW (410 hp) and a whopping 930 Nm (686 lb/ft) of torque. Alternatively, you could opt for MTM’s M-Cantronic device. Achieving the same performance figures as a remap, but for € 100 less, the M-Cantronic is much more refined than chip tuning; tapping the RPM signal from the CANbus to recalculate parameters of the engine´s characteristic diagram before specifying and applying new figures for fuel and boost pressure. For € 2,700, A8 owners can enjoy both the V-Cantronic and M-Cantronic.
MTM can also provide you with wheel, brake, exhaust and chassis upgrades for the A8, Q7 and the Touareg.
