This package includes multiple starter maps, Factory, 19.5PSI, 21.5PSI, 23PSI, and 19.5/23PSI dual tune activated by the Sport button. Also included are quick adjustments that give you easy levels of control for throttle response, partial throttle boost response, and turbo ramp lag. Pick the combo of settings that’s right for your testing needs!
