Dave:

When you converted to MPFI (batch fire) from TBI and installed the jumper of the MEMCAL, how much change, in engine running quality and, did you have to make to the off idle fuel map? The way it happened for me is that the engine ran rough. Did not have an AFR setup so don't know what happened. Will repeat with AFR setup to get clue as to what is happening. Any experience that can be shared would be greatly appreciated. Thanks for your response.
