Flexfuel injectors are actually larger...flow more lbs (like 34lbs vs. 27 lbs +/-)....than the regular fuel injectors to allow for the E-85. Unless you WAY oversize an injector, it won't affect idle, etc. much, if at all if tuned correctly.
Larger than the 42 lb ones you are using? Should make for a cheap junkyard solution if you needed more than 42 lb ones on just gas?

Not larger than the 42's....but larger than the typical pickup injectors. I just guessed the lbs for the 34 lb vs 27 lbs thing....every size motor is different....but flexfuel injectors are bigger. It would be interesting to see what a 6.0 flexfuel flows (if they make such a beast...I don't know). I know my 2001 Suburban 3/4 ton 6.0L is not flexfuel.
