Check the full match

Coverage includes supported Silverado, Sierra, Tahoe, Yukon, Suburban, Avalanche, Escalade and related GM LS combinations. Engine and controller support must be checked for the actual build; the year range is not blanket coverage for every engine offered in those vehicles.

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

The tune is developed from your supplied read and modification list, with follow-up feedback and logs used for revisions as needed. The listed service includes up to five revisions for the supported combination.

What to send before tuning

Have supported HP Tuners hardware, software and vehicle licensing available to read and write your vehicle. Provide the engine, transmission, cam, injectors, intake, exhaust, converter, gearing and tire size before tuning begins.

From stock read to revisions
  1. Choose the service or cam option and place your order.
  2. Use your private Tune Portal to provide the original read, vehicle details and complete modification list.
  3. Receive the tune through the portal, then provide feedback and datalogs for the revision support included with your service.
