I have it running my primary injectors. It's on an 8 psi setup and it works fantastic. It's it plug and play? No. But it's quite powerful for the price. Also it allows for much finer tuning.
Read a bit on it. There's a lot of guys (including me) who'd be happy to help. It is a bit more complicated than some other setups, so you should do what you feel comfortable with.
