Turn decoded vehicle data into the correct tune path

Decoder results help identify the build, but the final match still requires the actual engine, controller, camshaft, hardware, and modification list.

Build Your Tune

Select the vehicle and camshaft, choose the tune type, then add only the modifications supported by that path.

Tuning device required: You must have an HP Tuners MPVI2, MPVI3, or MPVI4 supported for your vehicle. J.R. Jones Racing LLC does not currently support RTD or TDN devices. RTD/TDN support is planned for the future. Check device requirements. Need an interface? You can add an HP Tuners MPVI4 to your tune at the bottom of this builder if you would like to purchase one through J.R. Jones Racing LLC. Vehicle credits are sold separately.
