Remember these are direct injection injectors not regular injectors, much different beast. Also in order to take advantage you will have to upgrade the high pressure fuel pump (HPFP) by going either with duals like the BMW and Mercedes or a bigger surface area on the piston. I follow the Mazdaspeed guys because their platform came out in 2006, they've given getting enough fuel from the DI setup and are now piggybacking PI on top of it, the same thing I'm currently installing this week on my Flex. I'll be able to report back some finding on my transverse ecoboost V6 on stock (smaller than yours) turbos with E85 within 2 weeks. Hoping to see well over 400WHP/450WTQ on my baby GT15's on E85 - that HP level got me to mid 12's on my Flex with my nitrous setup.
Sorry, should have been more specific, I work for a diesel fuel injection manufacturer. We are obviously well versed in DI. I know what modifications can be done to increase fuel output, but you have to balance those as you don't want to begin to impinge on the walls or the piston.
The research is what would be cost prohibitive. The tips we can have manufactured for relatively cheap. But the overall cost for sales in maybe the hundreds per year is not worth it.

I think it's volume we need...the rail pressures look pretty good (now I am talking way out of turn here---as I know very little about fuel).

It works almost identical to the Mazdaspeed DI setup if you are familiar with that.
Our HPFP falls off pressure under high boost, we need more volume on the HPFP to maintain the rail pressure.

So we have an in tank fuel pump that runs at 65 PSI that feeds a cam driven high pressure fuel pump. The excess fuel pressure is varied by both voltage control to the in tank fuel pump and a spill valve in the HPFP from what I understand.

Torque app for android phones can monitor rail pressure. It is all over the place from as low as 200psi up to 1200 ive seen.

Another thing I forgot to mention, we were able to get a little more fuel over on the FSI platforms but upgrading the stock LPFP as the factory ones did not seem to keep up and the HPFP was found to be waiting on fuel, starving essentially, in some instances. By upgrading the LPFP the HPFP was always kept under positive pressure with full line waiting to feed it even under the most extreme WOT instances. So every time it accepted fuel it, the chamber filled completely.
Same thing the diesel guys have been doing for years with the Airdog and FASS systems, as well as those remove air and water too.
