Diesel tuning boxes are devices that can be used to tune most diesel vehicles to give them more power. Most good quality diesel tuning modules can increase the power of a vehicle by up to 30 percent. A good quality diesel tuning box is usually digital and is suitable for use with vehicles that pull heavy loads such as taxis, 4x4's and light commercial vehicles.
Diesel tuning boxes can dramatically increase brake horse power, improve general drive ability, increase pulling power or torque, and improve MPG for drivers who travel long distances on a regular basis such as commercial van drivers.
The majority of diesel tuning boxes can be installed by anyone with a basic knowledge of cars or by anyone who can read a manual and follow simple instructions. Some tuning boxes only need a solitary cable to connect them. However the majority do need more cabling therefore can be slightly more complicated to install. Most tuning boxes are relatively small in size, when fitting a diesel box one should always consider the location for fitting and make sure it is away from water and high temperatures.
Diesel tuning chips are an alternative, but with these it is not really possible for a novice to carry out the procedure. Therefore it is best to have it done by a professional who knows what they are doing.
One good thing about tuning boxes is that with most of them you can alternate between different tuning maps without having to go to a specialist fitter. With tuning chips however the tuning map is usually tailored to your specific make and model of vehicle. Therefore if anything does malfunction you would have to take it back to the specialist. Any changes needed will have to be done in a garage or workshop.
It is always a good idea to remove any tuning boxes before taking the vehicle for servicing, due to the fact that most service shops won't work on a vehicle that has had any kind of performance modifications. Therefore it is always a good idea to have it removed first which should be quite simple. However with tuning chips it is best to go back to the original fitter to have it removed and returned to default mode before attempting to have it serviced.
Diesel tuning boxes can increase the overall power of a diesel vehicle; however it is always a good idea to seek expert advice before installing one.
