Xtreme-DI HPFP45 Direct Injection Pump

Is that done in the tune ?

Yes and will stop the high pressure drop

Octane doesn’t care if it’s direct injected or port injected.

on e85 at 1050-1100 wheel, we were able to add about 10% more di to the mix, with the stock di injectors

Thanks for the Info. I have heard new high flow DI injectors are in the works similar to the GM LT4 high flow units.

GM was supposedly supporting after market DI fueling VERY strongly with OEM engineering support.
Anyone hear of FORD performance DI pump in the works?

At what point is the Direct Injection system not a huge assistance to the overall fueling strategy? Clearly for e85 cars, the DI allows you to run oem injectors (19lb/hr) where as on the previous gen coyotes, you'd need ~47's. I'd think that at some point that assistance starts to tail off with the stock DI system?
