Please read the entire description below. If you have any questions please email!

Vehicles Supported:

  • 2015-2023 Ford Ecoboost Mustang, including HPP
  • 2016-2018 Ford Focus RS
  • 2014-2019 Ford Fiesta ST
  • 2013-2018 Ford Focus ST

Drop Down Options:

will cover tuning for your current modifications and your choice of fuel (see list below). Once the tune is completed, your purchase is finalized. The tuning process will account for any modifications* you have installed on your vehicle at the time of tuning, if you change or add any modifications to your vehicle that require a new tune you will need to purchase a ReTune. 

Dual Fuel ProTune: will be the same process as above, but allows you to select two fuel types (see list below) to be tuned for your current set of modifications. If you know you want to run multiple fuels for your setup, ordering this from the start will save you money. If you decide you want an additional fuel (3 or More) later you'll need to purchase a ReTune for each fuel. After you are tuned for all fuels and down the road you change the setup again on your car and require a new tune, a 1x ReTune purchase will cover all fuels you were previously tuned on. You do not need to purchase multiple ReTunes.

ReTune: is only for current customers that purchased a ProTune, or Dual Fuel ProTune previously. If you are a new customer you will not purchase the ReTune option, you must purchase a Protune or Dual Fuel Protune first to start the tuning process. 

A ReTune purchase is required if you were previously tuned and have made changes to your vehicle that require a new tune. Please see the list below of changes that require a retune. If the change you made is not on this list, you do not need to pay for a retune! If you were previously tuned for a single fuel and would like a tune for the same modifications but a second fuel you will need to purchase a ReTune if you did not originally purchase a Dual Fuel ProTune. Customers that originally purchased a Dual Fuel Tune will be retuned for both fuel types for the new modifications for a single ReTune price. 

After you purchase a ReTune you will submit your request for a new tune by clicking here or clicking the "Tuning" menu option at the top of the page.

Previous customers that purchased a tune before July 1st, 2021 please read below:

Single Tune Customers - As unlimited tuning upgrades are no longer an option you'll just need to purchase the ReTune drop down option if you need a retune for a new modification or fuel type. 

Unlimited Tune Customers - Nothing has changed for you. The only time you will need to pay for any additional tuning is if you add Port Injection or a built engine with aggressive camshafts that require Cobb's Custom Speed Density tuning. This will be discussed with you.
