    Seems a little goofy. KOEO map reading should show roughly 100kpa depending on altitude.

    Remove the 1 bar map channel aswell, only log the 2 bar or 3 bar channel so it can't skew the data logs.

    Without seeing the tune file it's tough to say what is limiting the RPM.

    Could be an abuse mode. Or an actual rev limiter that didn't get changed.

    The 5.3's and 6.0 from 2000 run the same sensors and injectors. Changing the calibration information to a 5.3 from 2000 will still work fine.

    Random thing here, disable desoot mode. That will stop a lean spike when you stab the throttle.

    You could try setting the traction control spark cut to disable as well.
