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, or an EFI Live device supported for your vehicle. JR Jones Racing 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 JR Jones Racing. Vehicle credits are sold separately.

Full Custom and Base support listed modifications. Downloadable .HPT files cover only an exact supported cam or delete calibration with no modification add-ons.
Modifications & Options
Stock / Short-Tube Headers — Included
Downloadable Files Do Not Include Modification Support
Downloadable .HPT files are limited to the selected supported camshaft calibration or supported DOD/AFM/MDS/VVT delete calibration. They do not include tuning changes for blowers, headers, intakes, injectors, fuel systems, heads, converters, transmissions, tire size, gear ratio, or other add-ons.
Supporting every possible vehicle, cam, and modification combination would require more than 14,000 separate files. If your vehicle has additional modifications, choose a Base Tune or Full Custom Remote Tune.
