I want a pretty low IDCs and have it be pretty reliable w/o getting maxed out. I originally was going to go w/ the STI injectors, but was told by a couple people that the IDC would be somewhere around 91% with the stis. So I was thinking about the PE 650cc or larger. Anyone have any input? Am I worrying about nothing or should I be fine w/ the STi injectors? Thanks in advance.
