That doesn't do it justice for all the effects it brings. I do agree that the port injection is the EASIER but not better means of increasing fuel flow for the engine. The higher your percentage of mass fuel from port, the lower you det threshold becomes, in comparison, just an FYI. I'm not one for cutting corners.
I plan on upgrading the DI side of things and leaving the port as they are now and used only in its limited region of lower RPM and higher load.
I do agree that upgrading port injectors is far easier and cheaper and I'll probably initially setup this way while I'm working on the DI upgrade route. I've already been speaking with a friend who works in the injector side of Siemens (where they've been wanting to get into the aftermarket-market) and working with the great guys at Deatchwerks. I still can't get an answer on how the DI injector sizing on the FA20 nor which HPFP it is coming with.
As for other market details, I shouldn't really spill too much yet. Many things are going to be beta-tester stuff, which I'm looking forward to
