Well it all depends on if you are tuned above stock and by how much because there is only so much fuel that can flow through a stock injector and the methods of releasing that fuel can be had through both FICM and ECM tuning so there will be limits to each but either way let's say you were at 420-430hp on a race tune with a stock set up. FICM tuning will get you the rest of the way to the max that your injectors will put out and should be good for 440-450 pretty easily as there are a few guys I have heard that have put down those sort of numbers with both types of tuning. Not to mention a smoother running engine, better throttle response, and fuel economy. JMO.
