- Peak gains are measured as the difference between the highest points of the two plots.
- Maximum gains are measured as the largest gain at any single point between the two plots.
Results may vary. Generally speaking, the 91 (95 RON) and ACN91 calibrations run slightly lower boost, have a richer fuel curve, and a less aggressive ignition advance map to help compensate for 91 octane (95 RON) fuel; Arizona, California, and Nevada 91 octane fuel; and/or less than ideal atmospheric conditions. The maps designed for 93 octane (98 RON) are the most aggressive.
