the 370z has both narrowband and wideband O2 sensors. the widebands don't seem very accurate below 12, so its not very useful when you need to tune for boost.
your first post was hilarious, but by the 2nd page it was incredibly clear you had not done enough research, it went from "im going to prove all of you wrong and makes tons of power with stillen!" to "FI is expensive here, i can get the stillen kit cheap, should I do it and just be happy with whatever i wind up making?"
theres 9 pages here, I'm not sure why, stay NA. if you can barely afford the FI kit, what will do you if you hurt the engine?
