Injector duty cycle question

Lets say you have a stock injector running 90% duty cycle.
You swap them out for a pair of 48lb hour injectors and the new duty cycle is 45%..

Will the new injectors give you better fuel milage??

Thanks

No, there should be no difference if tuned properly.

For driveability reasons, I would stick with the stock injectors. 90% is OK, and you won't have any funny lean/rich conditions you can get with injectors other than stock, strictly because no one can properly tune the pulse widths, and min injector pulses properly. Stick with the stock ones, or upgrade to the 28lb/hr, or some LS2 injectors.

What is significant about the LS2 injectors??
How many lb/hr are they??

Thanks

Just so you know the numbers I was saying are just made up.. I was just curious about the fuel milage issue..

I think I am going to need injectors soon when I do my heads and intake..
