Unless this is a collectors deal- and with you screwing with it - I doubt it, convert to a single TBI and EBL or TPI, should be dirt cheap units out there and a ton of info on Thirdgen.org. Lots of power in a properly prepped TBI. X fire is probably unpopular for a reason. Come to think of it- I believe EBL has an option for X fire, your biggest tool here is a decent cam and ecu.
