Calibration Strategy Information
See our Octane Adjust Ratio technical article for additional information regarding some of the strategies we utilize in these calibrations!
In order to keep the cooling system working efficiently in the most diverse array of conditions, the temperature threshold for fan operation has been lowered so that they come on sooner. This can also mean that the fans will continue running after your car is shut down. This is normal expected behavior.

Exhaust requirement: Stock exhaust, or COBB Cat-Back Exhaust 5M2150
Boost Level:
91 OCT or 95 RON Minimum Up to ~23.0psi tapering to ~19.5psi by redline. (+/- 3psi).
93 OCT or 98 RON Minimum Up to ~23.0psi tapering to ~19.5psi by redline. (+/- 3psi).
Stage2
Intake Requirement: Stock airbox with stock / COBB air filter 7M1101 or COBB intake system 7M1100

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.
