Trying to nail down what I need here, with a 2.3 tvs gen 2, looking to make close to 700rwhp on e85, do i need to go return style system. I asked this in the blower sub forum and it was reccomended that I get id1000s and a BAP. Is that all I need fuel wise. J see so many on here talking about full fore systems at similar hp levels. At what point do I need to go return style?
