  • Need more fuel for b6t

    I finally got in a vj11/tbird turbo and don't know how to add more fuel. At 18 pounds of boost and 7k rpms my wideband reads 13.0.

    J.T said I could put in thunderbird 370cc injectors but that would make me run rich everywhere. He also mentioned a rising rate fuel pressure regulator but said I should ask here first.

    What should I do to get more fuel other then turn down the boost?:p

    Edit: I am on a rocketman ecu and stock injectors with a walbro 255

    Have you run a larger power wire to the fuel pump yet ?
    Have you adjusted the vaf any ?
    Just some easy things that might help , wasn't this a half tank or less cutting out problem car ?
    Good luck .
    New build on the way .

      Please disregard this for a day. My poor craftsmanship is not letting the wideband read correctly. It's reading 17:1 at idle I know this is wrong. I have a couple exhaust leaks from the downpipe and my cutout is not sealing.

      The wideband will read better under throttle but is probably leaking even more leading me to a bad reading. Rocketman has said that his ecu will support this turbo and I know he is not wrong.

      Good things to think about. I will try these after I fix my current problems.
      It was cutting out cause the sock filter fell off, its now good all the way to empty.
