Hey finally a topic I can put some actual input into!!! IMO, from playing with the Crossfires handling vs speeds before and after chipping I have found this... After chipping, during hard acceleration on the same curve, as before the rear of the car breaks loose as the Wing comes up. My only explanation is that the car accelerates much faster now, and the wing does not rise overly fast. Now other things start to happen like the computer traction control cuts in... but the point is that this wing is functional and not just cosmetic... efficiency etc are not clear however.
