Notes: Stage1, Stage2, and Stage3 OTS maps have brake boosting enabled for 2 seconds. You will be able to floor the gas with your foot on the brake to build boost. The timer for the sport button has also been raised to 30 seconds so that you can enjoy the overboost feature for longer. The additions of any other hardware may cause the vehicle to perform poorly. If you experience any issues at all please contact our Porsche Expert Group at Porsche.Experts@Cobbtuning.com.

Closing Warnings and Precautions:

• Use of inappropriate calibration/modification combinations will promote engine damage
• Seek the help of a professional COBB Protuner should your Porsche Turbo fall outside of OTS map requirements.
• Top Tier gasoline should be used when available. Use of lower quality fuels can result in catastrophic engine damage.
• For track events, we recommend adding at least 2 gallons of 100 octane fuel to battle high track temperatures.

• If using E85 it is your responsibility to ensure you are getting the proper mixture from your station. Many stations change to an E70 blend in the winter. 

Revision Notes:

V103:

• Updated maps to add factory fuel PID oscillation issue to all Stage3 B742 maps as well as Stage1 & Stage2 B742 maps that were fixed in V102.  All 997.1 Turbo maps updated to V103 for conformity, but only B742 Stage3 maps have been modified.         

V102:

• Updated maps to correct a factory fuel PID oscillation issue unique to B742 ROMS.  All 997.1 Turbo maps updated to v102 for conformity, but B721, B730, B740, B821, and B830 maps are unchanged from V101.       

V101:

• Improved map stability and map maintenance update for future feature support. Initial launch of Stage3 Maps located on our website.  www.COBBTuning.com  
  

V100:

•  Adjusted load correction, load and torque limits, raised vehicle rev limits, raised vehicle speed limits, brake boosting enabled for 2 seconds. Also increased boost in both normal and sport modes. Made fueling changes as well as timing changes and raised the timer for sport mode to 30 seconds.
