Hi There, I have just purchased a set of headers for my P6 from ebay, item no. 232456041022. I already have an uprated stainless exhaust, cone filters, heads from a 1998 3.9, hurricane cam. I still have the SU's (early HF's I think (1972 3500S)The needles were uprated from the original BBG to BBW on the rolling road, but I am now hoping to be able to upgrade the needles again. Any advice on roughly what needles would be required to give more power from the increased air flow? Thanks in advance.
