I have a 383 with a mini-ram, and the injector bpw at 3500 is 9.2 ms or so, and at the same time it's going extremely lean-22.45 on WB afm. The fuel pressure is steady at 45 or so. I know I'm not making enough hp to exceed the capacity of my 30 lb injectors, is it possible the injectors are shutting down due to too great a duty cycle? The motor seems to fall off a cliff from 3000 to 3500. If it can struggle past that range, it pulls strong from 3500 to 5800. in that range the bpw is 8.2 ms or so. The o2 sensors are not on the same side, NB on drivers side, WB on pass. side. I'm using Tuner Pro RT, all the data looks right except for this condition. I've been chasing this for a long time, and any help/suggestions would be very much appreciated.
