Improved power and economy
Once the DPT has been fitted the effects will be felt immediately. With up to 30% more power and torque available, driving you diesel car will be a whole different experience, DPT can improve fuel economy which means more mile per gallon (MPG) and with rising fuel prices this can be an important factor. This is possable because the torque characterstics of the engine change and become fundamentally more elastic, therefore you can drive in town with fewer gearchanges. (a high number of gearchanges means continuously accelerating and braking which uses more fuel),.
Higher Torque=lower RPM=Lower Fuel Consumption
Why Don't the manufacturers do this??
You may have wondered why the manufacturer can have the same engine in different models but they can have different power outputs, this is not due to the engine mechanics as they are all built to the same standard, but down to the software installed on the ECU which governs the engines power output, Manufacturers do this because of strict emission regulations and tax bands especially for company car drivers, Many countries around the world relate their tax levels to the KW/BHP output of a vehicle
