Ok i have a honda civic 1998 ex turbo B20. I have a t3/t4 turbo with a rev hard exhaust manifold, intercooler, and external waste gate setup on 7lbs. I tryed to install the 550 today and it wouldnt idle my car unless i took a vacumm line off. I set my safc to -50 and it did nothing for idle. Is 550 to much? Or is my safc not working correctly. I also tryed to put 450 Dsm injector with the box that also didnt idle my car, i set it to -40 from 1000-4000 and it still didnt idle my car. I dont think my safc is leaning the injectors out, but i double checked the wiring and it correct.
