Match the platform
Gen III, Gen IV, Gen V and LV3 files must match the correct year range, engine family, controller and operating system before any changes are copied.
Find Your GM Tune File
Choose your vehicle type, year, vehicle, engine and file setup. We only show combinations with a matching JRJ file.
For supported Chevrolet, GMC, Cadillac, Buick, Pontiac, Hummer and other GM vehicles—including supported Gen III, Gen IV, Gen V, LS-based, EcoTec3 and LV3 combinations.
Built around the supplied file metadata
These are fixed Downloadable .HPT (HP Tuners) Tune Files, not one-size-fits-all GM files. Each product listing below carries its vehicle application, platform or controller family, engine, fuel, transmission or hardware notes, modifications, supported-vehicle cross-reference, compatibility warnings, and J.R. Jones Racing LLC delivery information.
Gen III, Gen IV, Gen V and LV3 files must match the correct year range, engine family, controller and operating system before any changes are copied.
Engine size, camshaft, AFM/DOD/VVT setup, transmission, fuel system and other listed modifications must match the vehicle you are working with.
Open your original vehicle read in VCM Editor, open the purchased file as the compare file, review the differences, and copy only verified changes.
Before you order
You need supported HP Tuners hardware and software, the required vehicle licensing, and a clean original read from the vehicle. The exact ECU/PCM, operating system, engine, transmission, fuel system, and hardware must be verified before using any file.
GM downloadable file questions
No. Read your vehicle first, open the JRJ file as the compare file in HP Tuners VCM Editor, and copy only applicable changes into your own vehicle file.
No. Model year, controller, operating system, transmission, engine code, camshaft and other hardware differences all matter.
Supported Chevrolet, GMC, Cadillac, Buick, Pontiac, Hummer and other GM applications include listed Gen III, Gen IV, Gen V, LS-based, EcoTec3 and LV3 combinations.

Select the vehicle and camshaft, choose the tune type, then add only the modifications supported by that path.
Enter the specifications shown on your cam card. Durations must be measured at .050-inch tappet lift—not advertised duration.
Full Custom and Base support listed modifications. Downloadable .HPT files cover only an exact supported cam or delete calibration with no modification add-ons. FIRSTTUNE20 is not valid on downloadable or pre-written .HPT/.CTZ files.
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.
Read every statement and check each box. This builder will not submit a Downloadable .HPT file until all seven are confirmed.
