Modification Level
  • Remote tunes are only available for customers using HP Tuners or SCT.

    HP Tuners is our preferred software for remote tuning GM and Mopar vehicles. We offer an HP Tuners device rental so you don't have to buy a device. To see if your vehicle can be tuned using HP Tuners, please go to
    ***Additional vehicle specific costs may apply***

    We prefer SCT for tuning Ford Vehicles, or for those vehicles with limited HP Tuners support.

  • Wide band o2 sensors are required so that we can measure and accurately calibrate your vehicle's fueling. A wideband will need to be correctly installed and wired in order to complete this remote tune.

    Some newer vehicles have wide band o2 sensors from the factory, and will not requrie an auxillary one. If you're unsure if your vehicle has one, please give us a call, or select the rental option.


    A few vehicles with factory equipped widebands:

    2011+ Ford Mustangs
    Ford Ecoboost Vehicles

    If you already have an aftermarket wideband, CONTACT US before purchase.
