GeneralTuning specialise in Chiptuning petrol and diesel engines for improved performance and fuel efficiency. We have years of experience tuning BMW engines to optimise for performance and efficiency.
We analyse your vehicle and can adjust the engine management programme, also known as the ECU (Engine Control Unit).This engine software is largely responsible for the behaviour of the BMW 3 SERIE M3 420HP engine and its fuel consumption. We can optimise the ECU for any car, van, truck or tractor.
In the case of the BMW 3 SERIE M3 420HP engine, our Chiptuning file is tailored for more power and torque, reduced fuel consumption, smoother acceleration and improved throttle response. By optimising the torque curve the BMW 3 SERIE M3 420HP engine produces more torque at lower RPM. This also means that you can change gear earlier, so your BMW engine will run at lower revs and therefore more efficiently.
Many engine Chiptuning companies all over the world choose GeneralTuning to tune their BMW engine. Our BMW 3 SERIE M3 420HP engine Chiptuning file provides the best possible performance and results within the original safety margins.
