Does any one no why my car would be running really rich when i have my ifr's set to what they are supposed to be for 42lb injectors and when i set them leaner to 5.507813 it runs really good and idles good now too. When i set the ifr's to 6.110675 it runs terrible. Ive looked at several tunes with 42lb injectors and none of them have their ifr's set as High as the injector calculater says they should be. I must be missing something or miss understanding?
