Tim hit the 400 mark with his ARP Turbo, not sure what the injectors were though.
I know we max'd Nige's 550cc injectors on a 20G but then is was a 2.5 block.
Simon would be able to confirm the max ability of the standard pinks, with maybe an FPR added for greater flow.
I've never really pushed the standard 550's on an STi with a Turbo upgrade so can't add much. All the turbo upgrades I seem to of done were WRX's fitting STi Turbo's and STi pink injectors, so obvioulsy they worked well together.
LOL..he had 650's, just seen the above
