Biggest Injectors w/ killing MPG

Im looking at getting some Flux injectors, I want to get the biggest set i can w/out to much of a drop in MPG. Ill be going with either twins (stocker/400) of the silver 62/64 and I have a Smarty and built tranny. And I do realize Ill need a modded CP3 if I get bigger stix. So any suggestions?

Do any of the 3rd gen injectors give you any mileage, in particular on my 03 HO?

On my 01 the Mach 1.6s gave me an extra 1 to 1.5 MPG.

My 90s are great. Highway is from 19 to 21 MPG. Street and back roads are 12 - 17 MPG.

I have a problem keeping my foot outta it, too.

I average around 18mpg or so with mine. With more air I'm sure it would be better.
