With it's dynamic timing the VE makes a better setup for lower power levels. You can achieve mileage and off idle driveability that's difficult for the P7100 to match.

A 250HP 4B in a <6000 pound vehicle is a pretty fun ride.
My Junker Drag truck is a pretty fun ride, 550-600 HP in a 5200 pound vehicle.
