My sr20det redtop was running very lean on a pretty much stock motor. My car ran from 16-18:1 to off the charts

so I installed a 255 walbro and a nismo fpr and its still running very lean. when i first started it it was idling at 12-14:1 and after letting it warm up and giving it some gas it idled at 16 to off the charts

I have an safc 2 ( relax im going into university ) but havent installed it, could I just adjust the fpr to help my leaning out issues? i really thought the new pump was gunna fix this problem.
