How would we go about calculating and recommending the appropriate injector size for the particular engine we will be tuning. Or as tuners we do really care and tune to the limits of the setup and make recommendations based on how the car is making power.

The key aspects we need to know are the estimated engine power, how many injectors will be fitted to the engine, and what fuel we are running. There is an injector calculator in the course or alternatively the fuel flow calculator on Injector Dynamics website is excellent. http://injectordynamics.com/injector-selector/
