Default Idling issues with big injectors (MS2)

what are the biggest injectors you guys are running on MS2?

i have hi-z rx7 550's right now... the car runs great overall but the idle AFR is a little wacky at times, despite a lot of time spent trying to get it dialed in perfect.

i'm seeing 85% duty cycle at full boost/redline so i'm considering stepping up to 650cc injectors for a bit more headroom. at the same time, i'd switch to lo-z... which should theoretically help it idle a bit better, right?
