That's an odd looking VE table. It's common to see Valleys and Peaks in a VE tables. The VE table posted appears to have Valleys and Peaks outside of the "normal" range.

Typically, an engine at low RPM's and light engine load will require less fuel than an engine at high RPM's and heavy engine load. Residential driving at 25 MPH requires less fuel than towing a RV trailer at 70 MPH. Typically an engine will require more fuel as it quickly accelerates to 70 MPH than an engine cruising at 70 MPH.

Timing is another variable to throw into the mix. There's basically one rule for timing . . . give the engine a timing table it likes. The real "heartbeat" of tuning is timing table tuning.

As an experiment, try add or subtracting a few degrees of timing to the corresponding " VE Valley Cells" of the timing tables.
