A higher octane fuel can be used safely on a mapdesigned for lower octane. DO NOT use maps designed for higher octane with lower octane fuels.Top Tier gasoline should be used where available. Sport maps are designated for use with 91 and 92 octane fuel or better. Aggressive maps are designated for use with 93 and 94 octane fuel or better.2311 W Rundberg Ln.

Typical Stage1+ COBB FMIC vs Stock Power:Stage1+ COBB FMIC Sport Peak +15% HP / +24% TQ Max. +17% HP / +25% TQStage1+ COBB FMIC Aggressive Peak +17% HP / +33% TQ Max. +19% HP / +35% TQAbove are the dyno results for a 2011 BMW 135i DCT on our in-house Mustang AWDDynamometer. Results may vary based on conditions such as particular model of vehicle,fuel quality, etc.Generally speaking, the Sport calibration run slightly lower boost, has a richer fuel curve,and a less aggressive ignition advance map to help compensate for lower octane fuel blends suchas those found in Arizona, California, and Nevada; and/or less than ideal atmospheric conditions.The Aggressive maps are designed for 93 octane and are the most aggressive.2311 W Rundberg Ln.

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 BMW N55 fall outside of OTSconfigurations.Top Tier gasoline should be used where available. Use of lower quality fuels can result in catastrophic enginedamage.Revision Notes: v100 – Original Release Calibrationo Stage 1: Adjusted boost levels, fuel, ignition, and base programming logic to improve performance andreduce ECU interference over vehicle driver’s input. Torque and load limiters adjusted or altered to allow forsignificantly increased power over stock levels. Fuel mixtures have been appropriately tuned for increasedpower levels to provide safety and performance.ooStage 1+ COBB FMIC: Logic and tuning parameters have been adjusted in order to capitalize onStage1+hardware. “Stage1+ COBB FMIC” mapping requires a COBB front mount intercooler.Stage2: Mapping Intended for vehicles with COBB downpipes or full TBE. Adjusted boost levels, fuel,ignition timing and base programming logic to improve performance and reduce ECU interference overvehicle driver’s input. Torque and load limiters adjusted or altered to allow for significantly increased powerover stock levels. Fuel mixtures have been appropriately tuned for increased power levels to provide safetyand performance.2311 W Rundberg Ln.
