Robert, At what AFR are you seeing this? I recently tuned my car to cruise in the high 15's and low 16's and shut off the injectors below 18kpa and i notice at light almost-coast the car bucks--presumably from a misfire. I'm going to try and make the transition from cruise fuel to coast fuel more abrupt to prevent the hydra from interpolating between lean and off (which results in super lean but not off).
spark size may not matter if there's just not enough fuel distribution in the chamber. Just a thought to maybe improve lean burn low end torque: I wonder if you can put a restrictor intake manifold gasket to raise port velocity and tumble to more evenly distribute what little fuel you have... something similar to how the VTCS works on the 01-05 cars. ie cover up the bottom half of the ports.
