What the Stage 2 label means
The stage2 suffix identifies this file as a modified tuning variant rather than a stock calibration. In tuning catalogs, Stage 2 generally describes a performance-oriented modification, but the label alone does not specify the changes to fueling, boost control or output. It also does not establish which supporting hardware, if any, the file requires.
The related catalog identifier 89663-60X23 identifies the Toyota calibration family used to distinguish this entry. The catalog does not describe the stock calibration’s specific behavior or document the changes made in this Stage 2 variant.
