I am getting mixed reviews while searching this. I have a 07 classic flex fuel truck. I got some fast 60# injectors and i am currently running a .3 bar spring in my wg. That is only 3.5 psi but i have a .5 bar that is 7.25psi that i would love to use with my stock pump cause there is nothing wrong with the pump and supposedly its a larger pump........
so my question is how much larger is the flex fuel pump than the stock and compared to a walbro or bosh where does it stand. Will it fully support a 6.0 with 60# injectors on 7psi of boost?

The Magnuson tuner and techs I spoke with told me that they like the flex fuel pumps for there higher capacity vs. the stock fuel pump. They do not require a booster pump. Flex fuel systems operate around 8 psi lower than stock but also come with larger fuel injectors. The flex fuel injectors in my truck are 38 psi vs stock injector (I believe) of 24 psi.. The Maggie 112 flex fuel unit doesn't include injectors or a booster pump as they feel the flex injectors and flex fuel pump are sufficient for this size model.
