    Post your tune...somebody may be able to help better that way?
    Problem is...now that Greg is selling his DVD, most people seem to be 'worried' about offering injector advice or info....but you may find someone who has had a good amount of success running these injectors who will be willing to help you.

    YOU ONLY NEED TWO TOOLS IN LIFE - WD-40 AND DUCT TAPE. IF IT DOESN'T
    MOVE AND SHOULD, USE THE WD-40. IF IT SHOULDN'T MOVE AND DOES, USE THE
    DUCT TAPE.
    IF YOU CAN'T FIX IT WITH A HAMMER, YOU'VE GOT AN ELECTRICAL PROBLEM.

    You need to log injector pulse width and make sure any changes you're making are affecting the pulse width. If not, you might be bottoming them out with the minimum settings, in which case you'll need to adjust the minimums, the voltage offset, or the small pulse adjust.

    sorry to bump such an old post but I haven't ran across my answer yet.
    When logging injector pulse width is there a PID that needs created to make a map of the table as it is in the tune? I have mine where it's driveable and well rounded but theres still a part throttle area where it cuts out. AFR all where I need it. Really feel like it's in B3701 somewhere but can't pinpoint it.
    I can get all the PIDS to create that table except for a Data output.
    Figured making a map would make it easier to track down.
