Before even talking about what the pump can flow, I'm sure no one here has actually checked an FPR with a compressor and a pressure gauge and actually seen that they ALL max out at 5.4 bar and that they can't increase fuel pressure above that. even if you feed it 3 bar of boost, it will still only give you 5.4 or 5.7 bar max.

I have no logs because I have a boost gauge (makes things easier)

I have been thinking about this and and came to the conclusion the larger injector are required sooner or later. Now i am waiting on 550cc EV14 and i will post back after install, will initially install with 3 bar fpr and if required will increase to 4 bar

Just to finish this up, purchase 550cc Ev14's and installed and never had an issue since, i strongly recommend to this method instead of increasing fuel pressure.

Definitely a worthwhile upgrade
