Since most people are using the PFC with the factory saturated injector drivers and some resistor, what are they going to use for the 3 injector overlap settings, the pri/sec transition % and Sec transition msec settings? How about lag settings? On the various 1600/1680 cc injectors out there, there are bunch of well documented settings to try for these. Whereas with the 2000cc injectors, you're reinventing the wheel or shoehorning in some other settings and hoping the car runs right.

Unless the setup really would require 2000cc injectors, you are just creating a bunch of work for yourself trying to get the staging right in order to eliminate lean or rich spots. It's one thing to try them for a personal experiment, but it's another to give someone advice of "oh put 2000cc injectors in, they're like 1600's but better." Rarely is one part hands-down 100% better versus another, there are tradeoffs to everything. Bigger injectors have more lag for example, although it can depend on the injector design (bigger low impedence injector can be more responsive than small high impedence injector).

You could say "oh, x tuner is going to take care of the staging." Well x tuner is running a business and doesn't see 2000cc injectors every day so he has no incentive to spend time testing. It's just a pointless purchase for somebody who just wants to drive their car and not fiddle with the tune all time.

Here is one for example;
