Ever research the devices that convert water into hydrogen and oxygen and burn the hydrogen along with gasoline for increased mileage.

Seems far fetched but my mechanic is going to try it on a test vehicle, a newer Chevy pickup. He should have it finished next month. He plans to invest under a grand. If it works and no error codes come up on MIL, then he plans to start an install business.

Is this theoretically possible for this device to work on a modern computer controlled car?
