Paid selections are matched to the existing Shopify tune add-on products and added with the tune. Free and unlisted details stay attached to the order.
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.
Downloadable files cover the listed cam or delete setup and do not include modification add-ons. If your vehicle has additional modifications, choose a Base Tune or Full Custom Remote Tune.
Shopify is verifying that the exact file is available for sale.
Open the library with this selection, then review the listed file details and all seven buyer requirements. If no matching file is listed, choose a remote tune built from your own read.
No closest file will be substituted. Choose a tune built from your own vehicle file instead.

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?
Tell Jason about the cam, transmission, converter or clutch, fuel and airflow parts, rear gearing and tire size. Those details give the remote tune a clear starting point and keep requested refinement tied to your car.
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
For a manual Camaro, include the clutch and gearing. For an automatic, include the transmission and converter. List any cam, AFM or VVT hardware changes; the LS3/L99 cam guide explains what to provide for those builds. Tuning a different GM car? See the Corvette cam guide.
Select the exact Camaro year, model and installed engine available in the builder. The transmission and cam are separate choices. Explain engine conversions and hardware changes instead of selecting another trim to make the build appear to match.
Straight answers
Camaro tuning questions
What changes between LS1, LS3/L99 and LT1/LT4 Camaro builds?
Start with the exact engine and controller, then identify the cam and transmission. For an LS1, include injector and airflow-meter details; for an LS3 or L99, document the clutch or converter and any AFM or VVT changes. For an LT1 or LT4, include the complete fuel-system details and any supercharger or turbo changes. Confirm the actual combination in the builder.
Can Base include headers and other modifications?
Yes, supported modifications remain available with Base and Full Custom. Select only what is installed, and review each selected charge in the builder's itemized breakdown.
Why do I need both the Camaro engine and transmission?
The same model line can contain different engine and drivetrain combinations. Selecting each accurately keeps the cam choices, service options and supported modifications tied to the actual car.
How do I describe an LS3 versus L99 Camaro?
Keep the actual engine identity and transmission clear. Chevrolet's LS3/L99 documentation distinguishes the AFM-equipped L99 used in fifth-generation automatic Camaro SS models. List any subsequent hardware conversion.
Can I choose a cam by brand name alone?
Choose the exact version offered for the engine. If the cam is not named, use the available cam-card entry rather than selecting a different grind from the same brand.
Will this service include a pre-tuned download?
This is a remote service built from your own read. Separately listed .HPT reference files use a different purchase and compare-and-copy workflow and do not include remote revisions.
Sources & application notes
Technical references identify the engine and equipment discussed. The builder and original stock read determine the selected application; these specifications are not a power-gain promise.
