Ok guys this might be a stupid question, but i am hearing two different answeres so I figured i better post it. I got a d15b motor just put in my 2000 civic and we used my old intake manifold with 395 injectors. Is that gonna make my car run bad or really rich or does the ecu control the amount of fuel going through the injectors and will keep it to the stock amount. IF that makes any sense.?! Thanks for any help

quick answer: it'll run rich and crappy.
the ecu can make adjustments based on input from the MAP and IAT sensors, but it assumes that when it opens the injector for X amount of time, Y amount of fuel will always squirt in. if you have an adjustable FPR, you can try lowering the fuel pressure to compensate, but that will probably have other adverse side effects and would just be a stab in the dark anyway.

Those are way too big...get some stock ones. Why were you running big injectors on the civic?
