If the engine is performing under par and requires readjustment.
When redefined optimum performance is required.
When an engine is properly tuned it is able to deliver more power and torque (pressurised force) resulting in a refined and powerful performance. Engine tuning is always worthwhile whatever the make or model of vehicle as it offers myriad benefits as well as extending the lifespan of the car.
A vehicle can be likened to the human body inasmuch as the engine operates similarly to the human heart whereby the mechanical heart (the engine) pumps power and torque throughout the components as the heart pumps air through the body. Therefore the stronger the heart, or the more finely tuned the engine, the higher probability that all other parts of the body, or the engine, will remain in good working order.
Let your vehicle breathe
In order to allow the engine to ‘breathe’ engine tuning is very much an integral part of the process. Fine tuning can release additional horsepower, well maintained filters, manifold etc. also define performance. A maximum efficient cooling system raises air mass which encourages free flow of air in the cylinders.
With additional pressure on engines, turbo diesels in particular, it is very likely that the original exhaust system should be replaced in order to allow this new level of power to flow unrestricted.
Intrinsic to engine tuning , and now we are talking about petrol engines specifically, is reaching the perfect air and fuel mix which, when it’s right, delivers effortless power without using additional fuel.Generally speaking vehicle engines require tuning for two reasons:
