    Attached is 16197427 MPFI Information.

    Maybe converting the 2.8 TBI system to the 16197427 TBI is a GOOD first step?

    My post for tuning the 16197427 with a Wide Band Oxygen Sensor (WBO2): http://www.gearhead-efi.com/Fuel-Inj...g)-Spreadsheet
    Post 25 has the latest spreadsheet. Post 26 has some useful screen shot for "Tuning" using WBO2 data.

    It's always challenging using parts from vehicles that are +20 years old in a project.
