Huh, that isnt how the DI injection system works at all. The DI injectors dont spray any fuel at the valves at all, no matter what change is made in regards to a different injector or a upgraded LPFP, or HPFP. The injector tip is physically inside of the combustion port and fires the fuel right into the chamber of the piston and the spark plug.
The only way to introduce any fuel back into the pre intake valve side loop is to add a port fuel injection solution that spray fuel into the intake runners in an atomized suspension. At that point then you will get some fuel wash across the backside of the intake valve.
