I have an 90 Rex SI w/ b16a1 swap, port and polished head, titanium valves, spring and reatainers, stage 3 cams and flow matched ITR intake manifold. All the other bolt on mods. I need a good tuning tool to help. it barely wants to idle(of course I knew this) But I can not get it from running rich. I was thinnking of an innovate unit since I can afford one! Any ideas are welcome!!
