Increasing the injector pulse widths would defeat the purpose, the extra fuel would have no more oxygen to burn & would just help with cooling, not power or mileage
Back in the 70s I read & saw pictures of a set up Crower Cams came up with to improve the milleage of a big block Chevy. Rocker arms were taken off on 4 cyl so the valves wouldn't open. Kind of oblong slugs instead of round pistons replaced the pistons so that the motor would not have to do the work of compressing air. I kind of thought a junkyard 283 with rings, inserts & valve job would be more cost effective, because of the big blocks recipcrocating & rotating mass.

I see what you are saying (I guess I'm slow tonight). So really the only way for the engine generate any boost (more air pumped than the other cylinders) would be have a ten cylinder that cruised with four cylinders working or some kind of holding tank.
