I noticed in Sean's email that if the PCM is not at it's latest version, the Calibration Update needs to be run before the custom tune can be installed. It also states that this will show up when trying to install the tune. I never noticed it until tonight, but it stayed that adjustments have to be made in order for the tune to install, but gives the option to confirm and goes forward with the writing of the vehicle. Is this "Adjustment" what Sean meant regarding the PCM version, or is this separate?
