any dis-advantage or potential benefits of fitting a 3.0 bar FPR to a b20, rather than the stock 2.5bar one?

I'm bored and fancied a tinker :D

it will increase how much fuel is injected, say you had a 100cc/min injector at 2.5 bar if you run it at 3 bar it will be a 109.5cc/min injector

If you have injectors that are down on their flow rate and are badly in need of a refurb., then it might well get you some more power, the same as the infamous 'ebay resistor' that goes in series with the coolant temperature sensor, but it's a far better idea to have the injectors rebuilt.
