    is there a way to make the car run leaner without having to mess with the ecu? my car is running rich right now; d15b2 with bumped compression(dont know wat ratio, but its about 210psi when i did compression test), short ram intake, and straight pipe.

    only things i can think of are hotter plugs and a new o2 sensor :dunno: ...your not really going to be able to touch the A/F itself

    EDIT:get a SAFC or a VAFC

    Install an adjustable FPR so you can lower your fuel pressure- that's about it.
