maybe you'll need to adjust the arm to the lean side. wierd 
they're high z injectors right?
you verified the o2 sensor is working?
another member also had an odd issue like yours. his ecu just stopped going closed loop. his problem was fixed when he replaced the ecu.

i could try and move it a couple clicks and see if it helps. and the injectors are from a 89 probe GT. i might get a new regualr 02 sensor, those are cheap. but the wideband it reading fine.

305cc injectors, RRFPR, check valves, Walbro 190HP, Bipes, O2 clamps, and you still can't tune it perfectly
vs.
460cc injectors and an MSPNP
Who's got more **** bolted to their car?

I don't know if i am correct... But how do you think the ecu is handeling injectors that are 50% larger than stock?? Normally very rich...
So you need to lower your base pressure below oem levels...
The only way i could think of is to make a bypass between the fuel suply and the fuel line between the afpr and the fuel rail. In the bypass you add a adjustable restrictor so you can adjust your static FP below stock levels.(tune that on your wideband)
At boost the afpr takes care of the rest...

they are only 30% larger and it can be done. I did it for over a year and made 240 miles a tank, consistantly.
something else is going on. you should be able to lean it out enough with just the idle mixture screw on the afm and it should be golden.
