why did it quit pulling?
just wondering if anyone could have an explanation as to why my truck quit making hp at around 5500rpms. my cam is in my sig. and it should pull well beyond that. n/a it pulled to 5900 and would have pulled farther if not for the truck intake. so why with the radix did it quit so early. it was pulling 10.5psi of boost until 5400rpms and then started falling gradually, but at 6000rpms it was still at 9-9.5psi. any opinions???
