So is the general consensus that having 4 850cc injectors is not a good set-up to have. I am looking for a simple injector upgrade, if there is a such a thing. If not then what size, brand, and where to get upgraded secondaries. I can get upgrade Blitz 850cc injectors pretty easily. That is why I was wondering. I have a Apexi Power FC and Commander not listed in my mods list in my sig. Thanks for any help.
