Dont mean to be "That Guy", but it doesn't seem that you guys have done the proper testing and research based on the products that you plan to bring to the market. Deleting the direct injection without offering a piston upgrade leads me to believe that you haven't looked into how doing so affects the way the factory DI piston design reacts to the extra heat. There is no problem with deleting the direct injection (though I dont see the reason for this other than tuners lack of ability), but doing so while utilizing the stock piston design will lead to a failure.
When I get back from the office ill point out some of the things that happen on a 2ur(ISF Engine) Piston when the direct injection is deleted and the heating/cooling dynamics change in the combustion chamber.
