Running a 4.5lb powerdyne with hot cam conversion and longtubes. I have an Ed Wright tune and 30lb injectors with an FMU and FPR set a 50 with vacuum line off. Car runs good but is a little rich. Will running a ported stock MAF or stock MAF with aftermarket ends help to lean car out or just the opposite? Or does this matter. I am currently running stock MAF with screens pulled. Thanks for any help.
