Calibration Strategy Information
See our Octane Adjust Ratio technical article for additional information regarding some of the strategies we utilize in these calibrations!
Closing Warnings and Precautions:
Use of inappropriate calibration/modification combinations will promote engine damage.
Seek the help of a professional COBB Accesstuner Professional should your vehicle fall outside of OTS configurations.
COBB OTS mapping is NOT designed to be used with upgraded aftermarket boost actuators or solenoids. Doing so may result in much higher than desired boost and potential engine damage. Seek the help of a COBB Accesstuner Professional should your vehicle fall outside of OTS configurations.
Top Tier gasoline should be used where available. Use of lower quality fuels can result in catastrophic engine damage.
Burnout Mode, Launch Control, and Flat-Foot-Shift (LC/FFS) are abusive to the engine, clutch, transmission, axles, and differential. The user accepts all risks and responsibilities when using these features.
Performance calibrations not designed for use when towing.
