SAFC, will not run rich under boost, what size injectors to go to?

ok well i got some 750cc injectors in my secondarys, and 550 in primary. I finally got a wide band, and turned the boost up to 10lbs, and with 50+ correction I can not get it to run rich enough it will stay around 13.5 and up. so since the SAFC is better at takeing away fuel then adding it, what size injectors should I go with. Would 1600cc injectors be just way over kill? Or could I cut it back enough? To get it tuned proper?
thanks
scot

what are your mods, adding 1600 with a safc is ovekilling it and if your running stock turbo 750cc are more than enough.

You anwsered your own question, you should have put the walbro furl pump in first then the injectors.
