Hey everyone I've been in process of rebuilding my 98 Cobra, I just purchased a v2-supercharger, I currently have a Wahlbro 255 pump installed Already, I have stock injectors, and MAF, I do have a diablo pred. Turner but have not installed any just cuz of ???? Regarding fuel & air, is a FMU necessary? What difference does the 90mm maf make and I'm not trying to overdue or blow out my engine since I spent lost rebuilding. Thinking of having it prof. Done with Dyno I've done everything else but these seems a bit outta my knowledge, any help greatly appreciated thanks
