GM LT based direct injection

[LTSonoma]

I see in some previous posts from a few years ago that DI control was at least being thought about. Are there any advancements in this topic? I am getting ready to start planning a project that will be a LT based turbo application. The hope is to run start up and cruising with DI and then port injection for any boost related tuning/running. Would definitely simplify, much less make injector purchasing much cheaper for a dual fuel setup. Also need to start getting cam shaft specs going. Basically need to figure out if I need the fuel pump lobe on the cam . I already have a Nexus R5 and would love to be able to utilize the DI injectors.

Any help is appreciated.
