You're not going to get any increase in performance from injectors. The only reason you would want better flowing injectors is if you increased the displacement or placed some type of turbo or supercharger on your engine. The Motronic system does a very good job of suppying just the right amount of fuel - too much, and the car will run rich, which will decrease power and efficiency.

What is it exactly that you are looking to do?
