How we work through your revisions
Revision 1 is guaranteed within 24–72 business hours after JRJ receives your stock read. The tune is based on your original read and the build details you provide. Follow the delivery instructions and report how the vehicle behaves.
Base Tune includes two revisions. Full Custom includes datalog review and up to five revisions for the purchased setup. The next adjustment depends on the logs, feedback and issues identified; there is no fixed sequence that fits every build.
After Revision 1, progress depends on vehicle condition, installed parts, mechanical or installation issues, tuning equipment and the quality of the logs. It also depends on when you have time to log and upload, when JRJ receives usable files and the time needed to review them.
Logs and follow-up requests enter the queue and are handled in the order received. Waiting for logs, answers, parts or repairs pauses the next step. A new submission does not start another 24–72-business-hour guarantee.
JRJ will work carefully and in good faith to help with your purchased service. Remote tuning cannot guarantee perfection, mechanical stability or a specific power result. Review the service and refund terms before ordering.
What changes in the tune?
Start with the actual engine and cam, then list the intake, exhaust, fuel and drivetrain changes. That gives Jason the complete truck setup while the builder keeps the service, cam and modification charges visible.
Startup & idle
Starting airflow, idle control and in-gear behavior are reviewed against the cam and operating data. Describe when a stall, surge or restart problem occurs.
Airflow & fueling
Provide the intake, injectors, fuel and sensor information. Relevant airflow and fueling changes must be assessed with the correct component data.
Valve & torque control
Select the cam and any installed cylinder-deactivation or VVT hardware changes applicable to your engine. The tune must reflect the parts actually installed.
Transmission & converter
Identify the transmission, converter, tire diameter and axle ratio. Their effect on the driving experience belongs in the build information.
The controller, service selected and installed hardware determine which adjustments are available. tune is not a repair for incorrect mechanical installation.
Have these details ready
- Select your year, make, model and engine in the dropdowns
- Select Stock Cam or the exact installed cam from the full list
- Original stock read, controller and operating-system ID
- Installed cylinder-deactivation and VVT hardware, where equipped
- Transmission, converter, axle ratio and tire size
- Injectors, fuel type, intake, exhaust and other changes
Choose the actual engine code before choosing the tune. A replacement engine, a 2007 Classic and a newer-body 2007 truck need to be identified by their installed engine and controller, with any changes explained to JRJ. See the application details for your 2003–2006 Silverado 5.3L or 2014–2018 Silverado L83.
Enter the exact Silverado year and installed 5.3L engine. The engine selection keeps the generation and cam choices together. Different engine codes and replacement engines must not be treated as interchangeable because they share 5.3L displacement.
Straight answers
5.3 Silverado tuning questions
What if I only want a downloadable 5.3 file?
Use the separate file library and review the exact application, file details and included instructions. A downloadable .HPT file is a different purchase and does not include this remote tuning service.
What if I have changed DOD/AFM or VVT hardware?
Tell JRJ exactly what is retained or replaced and identify the installed cam. Choose the remote service for a performance-cam build; delete-only work has a separate scope.
Why does a 5.3 Silverado need an engine-specific tune?
The 5.3L name spans different engine and control-system combinations. The selected year and engine, plus the original read, identify the correct starting point for the tuning work.
Does Stock Cam mean I must choose Base Tune?
No. Stock Cam describes the hardware, while Base and Full Custom describe the service. You can choose the available service for a stock-cam build and add supported modifications.
Are Truck Norris and Chopacabra included in Base?
Base includes the standard cam charge for applicable Truck Norris, Chopacabra and standard Stage 1 choices. Any higher-stage charge and selected modifications appear in the itemized total. Review the current price for your exact selection before checkout.
Can I add intake, exhaust, tire and gear tuning?
Choose the supported modification options shown for your actual truck. They are available with eligible Base and Full Custom builds, with the costs listed in the breakdown.
