Chiptuning for 303

Puretuning is a specialist in Chiptuning petrol and diesel engines for performance and fuel efficiency. We have years of experience remapping Challenger agricultural engines to optimise for performance and efficiency.

Many Chiptuning companies around the world choose Puretuning for tuning their Challenger engines. Our Challenger 660B 8.4 303HP engine remapping file provides the best possible performance and results within the original safety margins.

The benefits

In the case of the Challenger 660B 8.4 303HP 303hp engine, our ECU remapping file is tailored for more power and flatter torque, reduced fuel consumption, and an improved throttle response. By optimising the torque curve the Challenger 660B 8.4 303HP engine produces more torque at lower RPM. This also means that you can change gear earlier, so your Challenger engine will run at lower revs and hence more efficiently.

The process

We analyse your tractor 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 Challenger 660B 8.4 303HP engine and its fuel consumption. We can customise the ECU for any tractor.
