Modern turbo diesels and high power straight diesels can benefit from what is known as diesel tuning. In actual fact, the process involves replacing stock data used in the engine management system with engine management data that is specific to your driving style and the conditions in which you drive most frequently. The gains achieved can be huge although they will typically depend on the make, model, and engine of your car.
There are a number of benefits to buying a diesel engine when compared to petrol engines, and the modern diesel can deliver a consistently good level of performance. However, the engine management system in your diesel uses data that is designed for use in all cars or the same model. Manufacturers must make allowances for different driving conditions and styles and even need to accommodate those that use substandard parts, petrol, and oil.
Diesel tuning will use customised data so that factors like diesel usage and petrol flow are customised more to your driving style. When you put your foot down you will enjoy improved response and you will experience and endure fewer flat spots throughout the range of gears. If you use these improvements well you can enjoy improvements in power and also in your mpg fuel economy figures.
