Auto Octane: Automatically adjusts to the fuel you use; offers maximum flexibility (supports​​ 87-93 and e30).

• Best for: Relaxed driving and commuting; Areas with limited availability of mid-grade or premium fuel.
• Tune-Only Gains: Max gains on 93 octane. Marginal gains expected on 91, and mild gains expected on 87.
• Note: Functional refinements and improvements from tuning still apply on standard / mid-grade fuel, but will not necessarily result in a measurable increase in power.

91+ Octane: Self-adjusts to maximize gains of 91 or greater octane fuel (supports​​ 91-93 and e30).

• Best for: Relaxed and spirited driving; Areas with limited availability of premium fuel.
  Tune-Only Gains: Max gains when running 93; Gains when running 91 are approximately 15% less.
    

93+ Octane: Accepts 93 octane fuel or e30.

• Best for: Performance-oriented goals, towing, spirited driving; Areas with consistent availability of premium fuel.
• Tune-Only Gains: Max gains of all pump gas tunes. 

e50: Accepts fuel with an ethanol content of 40-60%

• Best for: Performance-oriented goals, maximum gains and competitive use; Areas with consistent availability of e85. Note: This fuel type is compatible with the stock fuel system.
• Tune-Only Gains: Varies by platform; greater than gains on pump gas by 15%+.

e85: Accepts fuel with an ethanol content of 70-90%

• Best for: Casual or spirited driving; Areas with consistent availability of e85 that testes between 70-90%. 
• Tune-Only Gains: Varies by platform, fuel system & modifications. See note, below.
• Note: Requires proper capacity fuel system to match the maximum airflow potential for your setup. If the fuel system is not properly sized, ethanol content may need to be reduced to match the maximum potential of your setup.

STANDARD TUNES provide a traditional custom tune that calibrates the vehicle according to one tuning goal: Daily Driver, Performance, Race, or Tow.

• Tuning goals for Standard Tunes are made at time of purchase. 
• Towing should only be done on the stock tune or with a Towing Tune (always in Tow Mode).

DMS TUNES provide a unique custom tune that individually calibrates each drive mode (Normal, Sport, Eco, Slippery, Deep, and Tow). DMS is like having multiple Standard Tunes at once, and allows you to switch tuning goals by turning the dial.

• Options for drive mode calibrations are: Stock, Daily Driver, Performance, or Race.
• DMS mode/goal selections are made post-purchase. 
• A Towing Tune will be placed in Tow Mode for all DMS Tunes.
• Tuning goals per mode are selected post-purchase.

Example DMS Tune Layout: 
•    Normal Mode = Performance Tune for 91+ Octane
•    Eco Mode = Stock Tune for 91+ Octane
•    Sport Mode = Race Tune for 91+ Octane
•    Slippery Mode = Stock Tune for 91+ Octane
•    Deep Sand/Snow Mode = Daily Driver Tune for 91+ Octane
•    Trail Mode = Stock Tune for 91+ Octane
•    Tow Mode = TOW Tune for 91+ Octane
 

Note:   

• DMS Tunes: Not yet supported for this platform. Tuning Goals are selected post-purchase, in your first Tune Request.
• Standard Tunes: Tuning Goal is selected at time of purchase. 

Think of your Tuning Goal as the foundation or starting point of your custom tune. Each goal influences power output, throttle response, transmission behavior, and overall driving feel differently.

• Tow - Slight horsepower increase, optimized for towing and low-end torque.

• Stock+ (DMS Tunes only) - The factory tune will remain in the selected drive mode.  

• Daily Driver - Moderate horsepower increase; Refines stock ECU and Transmission behavior for balanced performance and comfort.

• Performance - Significant horsepower increase; enhance aftermarket modifications, improves throttle response, and delivers faster, firmer shifts.

• Race - Max horsepower increase; aggressive tuning for advanced mods or competitive use with the fastest, and firmest shift strategies.

Gains will depend on several factors, including: Fuel type, tuning goal, and modifications (if any). 

Tune-Only Horsepower Gains Up To: 

After purchase, please submit a Tune Request (for Additional Tune).

• We do not send any tunes unless a Tune Request is submitted first.
• Syncing or reading new files is not required for this request - we will base your additional tune off of your existing completed tune(s).
• You'll receive an email with data logging instructions once your new tune is ready to apply.

As a best practice, we recommend flashing your e50 tune at the pump before adding ethanol.

While flashing issues are very uncommon and typically temporary, this approach minimizes the chance of any flashing-related interruptions.

After the tune is successfully flashed and ethanol has been added, drive a minimum of 15 miles before going into boost. This ensures the fuel is fully mixed and clear of the previous fuel type.
