Ford had to add port injectors to its Eco boost DI engines. Why? Carbon builds up. Most of the race shops are adding a second fuel system and port injectors on the newer DI engines like the LT's. It much simpler than trying to get more fuel out of the engine driven pumps. I think we have reached the point of diminishing returns for the cost and complexity of the new engines in the terms of horsepower and mileage. They are awesome but at quite a cost.
