    7.3L Powerstroke ECM rebuilt strange row labels/normalizers

    Any 7.3L Diesel guys that can take a look at these bins, one from the old ecm has been tuned and one from the replacement ECU, the replacement ECU has a strange row labeling in the ENGINE//TORQUE MODEL// TORQUE CALCULATION// INVERSE and the INVERSE ALTITUDE tables, wonder if someone could take a look at them?
    maybe point me in the direction to any good articles on tuning the 7.3L which tables do what?

    Anyone with 7.3L experience?
    IPR shows 65% during a WOT run, Injector Control Pressure shows 1981-2061 psi at 2900-3000 RPM,
    I believe 65% is maxed out, I was expecting closer to 3000 PSI, am i wrong?
    does the throttle Pedal voltage have much to do with WOT power I am at 3.97v.

    Someone here has more information, hopefuly they will chime in, no matter which chip or software they use it is sort of all the same thing with different descriptions

    I was also hoping to have more parameters to log in HPT, but looks like switching back and forth with a handheld scanner is all I can do

    Replaced the new ford HPOP again with a higher output pump. now getting 2800+ PSI at 40ish% on the ICP. replaced the factory ford fuel pump (which was new) with a better style pump with bigger lines now fuel pressure holds up at full load, Replaced a bad (new) ford ICP Sensor, still have too deal with codes for high boost and high Exhaust back pressure under full load
