Sounds like it's coming along quite well. Getting
the ve table accurate is the first step in the drivability
equation. I take it that you got the lean-mid-range-38lb-
injector discrepency cleared up? Great.

Drive braking is one way to get to those tables areas
that are hard to at <g>. I was always looking for
steep hills, hmmm.
