Good info, I'll check that out. Admittedly, we never did the test ourselves, but a couple years ago when planning for port injection, I had multiple reputable people, including TooHighPSI, suggest that I retain my upgraded DI parts versus selling them. All of them said it'll make more power the further we can push DI before needing the PI. Monetarily, that was a bummer because much of the PI cost could be covered by selling my upgraded DI pump and injectors, but I'm also always going for max effort of whatever parts are on the car, so I kept them.

The other bummer is that there is a high likelihood the aftermarket DI parts aren't going to be as reliable as 100% OEM. I'm on my third LPE Big Bore (various reasons for failures) and second set of +30 injectors now.
