Running a fuel tech ft550. No matter how I adjust the closed loop target table, my afr is still reading 12:1 on my nano pro. I adjusted the FP regulator from 71 psi to 58. Nothing except it ran crappy. I tried fuel trim. Helped a smidge. Maybe I have open injector? I just had them flowed(Bosch 210). Not sure what to try. Any help is appreciated
