It combines cutting edge technology with the simplicity of a modern smart phone! Intuitive, versatile and user friendly.

ECU Remapping

ECU remapping will not only improve the engine power and torque figures; it will also sharpen the throttle response and widen the power-band. This will make the power delivery a lot more linear, which in turn will make the vehicle feel a lot livelier to drive and the engine more flexible.

Hardware Modifications

Our extensive range starts from a simple DE-cat pipe to a full stainless-steel exhaust system, from a panel filter to a full intercooler upgrade. These performance parts can all be fitted by our experienced Tuning Consultants at our main tuning facility.

DPF & EGR Solutions

A Diesel Particulate Filter (DPF), also known as FAP on some French vehicles, is a device fitted to the exhaust system of modern diesel vehicles to reduce emissions and meet European emission standards. As with any type of filter a Particulate Filter needs to be cleaned regularly to function properly.

4WD Dyno Cell

SA Tuning has a fully equipped 4wd Dyno cell. This is a chance for you to see exactly what BHP your car is running. A graph is produced after each Dyno run and a copy will be supplied to you. We can also perform before and after Dyno runs when you have a remap with us.

PPF Solutions

A Petrol Particulate Filter (PPF), also known as GPF or OPF on some vehicles, is a device fitted to the exhaust system of modern Petrol vehicles to reduce emissions and meet European emission standards. It does this by trapping soot (Particulate Matter – PM) from the exhaust gasses while letting the gasses flow through the system.
