    You can leave it displaying AFR is that is easier for you. Most aftermarket Wide Bands display Stoich (1.000 Lambda) as 14.68 - in your case it would actually be around 14.3 - not enough of a true...

    Yes sir - something is indeed odd.

    The tune you loaded prior to this one, had much more airflow in the MAF calibration - which yielded WOT AFRs in the low 13s.

    TunerPro (with the correct XDF) is used for editing your calibration.

    To read / write your calibration (using an interface like the SX) you need to use an application like LS Droid or PCM Hammer.
