As Ziggz has said, the mixture can be kept constant. If restricting the injection to direct, for emissions at that rpm, is restricting the the available power then keeping the port injection operating will restore that power. The fuel consumption might suffer slightly because direct injection is more efficient and the emissions would be slightly higher but let's face it, they look to have done this to pass specific rpm emission requirements which is bending the rules anyway.
