[QUOTE="Midnight_Cobra, post: 15691258, member: 20927"] As far as I know the FPDM just supplies voltage to the pumps depending on the need for fuel. It MAY be possible it's bad, however if you put the stock one back in and idle and rev it up to see if the problem persists. If it does, you know the problem is somewhere else. If the problem goes away, put the modified one back in to double check. I have dual FPDM's so I don't have to worry about the single setup. I went from the stock pumps with BAP and single FPDM to GT Pumps and dual FPDM's without the BAP. I had my tuner install everything and check the tune afterwards. As far as I can remember, he didn't change anything in the tune, just double checked the A/F and timing on a few runs. [/QUOTE]
