There are lots of variables that you can change and retarding the intake cam does sound like it would decrease dynamic compression/horsepower/torque which should decrease pumping losses in theory and less power would requier less fuel, but altered ignition maping along with fuel mapping with vvt timing should make this combo work pretty good. Vvt would retard intake cam while you're cruising and when you need more power it would advance the intake cam to gain more power. It would be tricky to get igntion/vvt/fuel timing to work all at the same time on top of other variables like map sensor, air intake temp, engine coolant temp, oxygen sensor, bap sensor, tps sensor.
