Check the full match
Supported applications span GM LS trucks, SUVs and performance cars with the listed engine combinations. For a swap or a modified fuel system, submit the actual engine, controller and supporting-parts details. The body model and cam name alone do not determine the tune.
This service is built from the information and files you provide. Tell JRJ about every modification and resolve mechanical issues before tuning. Ask about unsupported or unusual combinations before ordering.
What the service includes
JRJ reviews your original read and build information to prepare the tune. Customer feedback and datalogs support follow-up changes for the supported setup. Revision support is included in this service.
What to send before tuning
Confirm supported HP Tuners or EFI Live equipment for your exact vehicle before ordering. Hardware, software access, credits and licensing are separate. Include your cam card, transmission, converter, injector information, gearing, tire size and all other modifications.
From stock read to revisions
- Choose the service or cam option and place your order.
- Use your private Tune Portal to provide the original read, vehicle details and complete modification list.
- Receive the tune through the portal, then provide feedback and datalogs for the revision support included with your service.

The download range is a separate purchase path for experienced HP Tuners users using Compare & Copy. Browse by the actual engine and cam combination; those files do not include this remote tuning service.
