@TwinDad
You seem to be the expert on the matter. You're the only one with Reflect Tuning map for the HPFP.
I remember Ian Nelson in the Golf R-GTI fcbk group posting about it.
I've tried tried swapping to the 2lt HPFP but 3 different tuners here in Greece couldnt figure it out hahaha...
Im maxed out at the moment making 325-330whp (370-375hp crank)...requesting 25 psi constant boost up to 7000rpm and the HPFP at 2900 psi.
But when weather gets colder the HPFP cant keep up with the increased fuel demand cant keep the specified AFR so pressure drops so does boost and in extreme cases I have sudden boost/fuel cuts and rail pressure drops to 2500 psi just to prevent the car from leaning too much.
My question is....would it make any difference to run Golf R injectors with Stock HPFP.
I know a guy in the UK that tried this out and made ZERO difference...
