Ok guys I bought this car with a n2mb box already on it. I havnt touched it.. dont even know how it works. My car is a 2.75 upper only cai offroad x and maggi catback. When i shift at wot it bogs back fires blue flames than goes agian. It seems like its over fueling or something. My MAF counts at wot are peaking 992 in 88* weather. Anyone have aby similar prob?
