Howell TBI troubleshooting

Anyone out there with one of these on a Jeep?
I am having rough running conditions-maybe too rich-not sure on this. This symptom is sparadic which is making this difficult to track down. I have gone through troubleshooting guide, not throwing any codes and am a loss right now what else to be looking at. I spoke with Howell directly about my fuel pressure at 14 lbs and this may be slightly high. Before I take the TBI pod off and start messing with pressures I just want to know if anyone else has had similar problems and what to look for.
