Brew City Boost is proud to present the ultimate custom tuning for your EcoBoost. By re-calibrating your vehicle’s computer for Maximum Horsepower & Torque, Increased Throttle Response, Firmer Shifts and even Increased Fuel Mileage.


This product is a single custom tune file for a Cobb Accessport (purchased separately). Qualifying revisions would be for the same turbo / fuel system / fuel type at the original purchased tune(s). If you change your turbo, fuel system, or fuel type a new tune would be needed.  Lifetime tunes (unlimited revisions) are also available for purchase. 

Three Datalog Reviews come with the purchase of a Custom/Ethanol Tune. 

About Tuning Slots: Up to 4 additional map slots are available to use on an Accessport. These map slots can be used for tune variations such as 91 octane fuel, 93 octane fuel, e30 fuel, 100+ octane race gas, and methanol injection applications. Select any additional maps you would like.

About fuel types: Fuel grade plays a very important role in the type of gains that can be achieved in tuning an EcoBoost engine. Lower grades of fuel such as 87 or 89 octane are more prone to pre-ignition, while higher grades such as 93 octane are less prone to pre-ignition. The higher grade of fuel run allows us to tune for more spark advance and boost, which translates to more power. Running an ethanol mixed fuel is an inexpensive way to increase the octane rating of your fuel. 100+ octane fuels are typically used only on race tracks.

About Tuning for Upgraded Turbos: An upgraded turbo is a great way to increase the power output of your engine. Typically tuning a big turbo is a bit more involved compared to a stock turbo. If you’ve upgraded your turbo let us know the specifics and we can optimize the tune for that specific model.

About Tuning for Upgraded Fueling Systems: If your vehicle has an upgraded turbo or is running on higher concentrations of ethanol an upgraded fuel system may be needed. If you’ve upgraded your fueling system let us know the specifics and we can optimize the tune for that setup.

  • Methanol: BCB can also tune for methanol injection. If you are running a meth kit please provide the details in the “What mods do you have field”.
  • Ethanol: Running an ethanol mixed fuel is an inexpensive way to increase the octane rating of your fuel. The percentage of ethanol a stock vehicle will support will vary by production year, or if the vehicle has an upgraded HPFP. If you live in a colder climate an ethanol mixed tune may not be advised to run in the winter. 


Our website provides a good calculator for estimating ethanol mixtures:


When running ethanol blended tunes you need to monitor the concentration (as actual ethanol percentages will vary with seasons / sources). The ideal way to measure would be this kit:


This tester will also work for testing ethanol concentration:


Upgrading the stock HPFP will provide more capacity to run higher fuel volumes (and higher ethanol percentages):


If you are unsure of which ethanol blended tune to select please call us for a consultation.


About Spark Plugs: Spark plug gap on tuned EcoBoosts should be set at 0.028″.


This tuning product is not compatible with other plug in tuning devices like BoostMAX, PedalMAX, Scorcher Module, or similar.  Likewise, manual boost controllers are not compatible. Notify us of any and all modifications prior to tuning.

*Brew City Boost will not alter emissions monitoring systems (O2 sensors) via tuning.

*Tuning slots for Raptors works a little differently, separate tunes are necessary for other octane tunes.
