    Question OS Calibrations

    Howdy all,

    I have this 2002 Lingenfelter twin turbo 427 vette here on the dyno.
    The car is down about 80-100 rwhp from expected. We have 516 on the printouts and the cars logged estimated rwhp is 511. Should be at least 600rwhp for a 725hp motor. And it is running in the 10.5:1 afr's under boost.
    The associated people at Lingenfelter would like to see a copy of the calibration to see if it has changed since it left their shop 6 years ago.
    Using the Tune software I uploaded the calibration data from the chip and saved it then e-mailed it. It was labeled as Calibration OS 12593358 custom calibration.
    However when I opened the file all I found was PID description info.
    What I need to know is how to copy the correct calibration info.
    Do I need to connect with the ECM, upload the current file, save it as a new tuning file and then e-mail that off to Lingenfelter?
    Thanks in advance- The Spindoctor (Tim H)

    Yes, that's correct.

    Yes, that is what I did as described in the attached picture.
    I will re save the tune file then ship it off.

    Thanks once again.
