He also mentioned a technical reason as to why the two Ferraris were swapping places so often during the San Marino race. "The (Ferrari 126C) turbo pressure was very, very difficult to control. Most of the reason that they were able to pass one another so evenly was that one would go through a sticky patch and sort of only be giving 4-bar of boost or 4.2, and the other would be getting a burst of 4.5, so it would have the legs of the other guy. It wasn't quite as spectacular as it appeared at the time."
