Installing smaller injectors to reduce consumption.

Anybody ever tried to use injectors that have less flow to get better mpg's ?

either A. it'll run lean, the O2 will compensate, and no change. or B it'll run leaner than the O2 can compensate for which could damage the engine. like running a turbo without adding bigger injectors.

The way to do it is run smaller injectors preferably with a more efficient design (4 pintle or something) at higher pressure. Then you get better atomisation, for the same fuel, this may translate to better burn and the ECU will actually lean them back a little.
