One of the things I don't really like about the new cars is that when I rev the engine, the rev carries off rather than snap back to idle. You can't really throw a heavier spring on it like the old carbed cars. I know the programmers help with throttle response. Do they help with this?
question, why would you like to reduce the "throttle hang"?
it´s better when accelerating hard and shifting...
(on the other hand, when you upgrade to a light flywheel and pullies, you´ll also notice it revs faster and the snap back to idle will also be faster...)
