Build your Corvette cam tune
Choose your vehicle and exact cam, select Base or Full Custom, then add your installed modifications.
HP Tuners required · equipment & credits
Requires supported HP Tuners MPVI2, MPVI3 or MPVI4 equipment for your exact vehicle. Hardware, licensing and required controller access are separate. RTD and TDN are not currently supported.
Vehicle first. Tune path before modifications.
Choose each part of the vehicle in order. After the camshaft, confirm the transmission and drivetrain, then select the tune type so the builder can show only the options supported by that path.
Doing an engine swap? Choose the original year, make, and model for your engine and PCM. Select “Swap Tune” below to enter the vehicle it’s going into.
Enter the specifications shown on your cam card. Durations must be measured at .050-inch tappet lift—not advertised duration.

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?
Give Jason a complete description of the Corvette's engine, cam and drivetrain. With Full Custom, requested logs and feedback guide the included revisions through the same Tune Portal order.
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
Include the Corvette's generation and exact engine, then list the installed cam, injectors, airflow meter, exhaust and any boost hardware. Add the transmission, clutch or converter, gearing and tire size. The LS3/L99 cam guide covers related engine details; the Camaro guide covers the separate Camaro application.
Choose the exact Corvette year, model and engine listed in the builder. Identify the installed transmission and cam, and describe any engine, controller or drivetrain conversion. Do not assume a Camaro tune is appropriate because an engine name matches.
Straight answers
Corvette tuning questions
What should I provide for a C5, C6 or C7 Corvette?
For a C5 LS1 or LS6 build, include controller, injectors, airflow meter and cam details. For a C6 LS2, LS3 or LS7 build, also record the clutch or converter and any boost hardware. For a C7 LT1 or LT4 build, include the complete fuel system and any cylinder-deactivation or forced-induction changes. Select the exact supported combination before ordering.
Does the cam name determine all supporting parts?
Follow the actual manufacturer's requirements and identify what was installed. JRJ needs the exact cam card and relevant airflow, fuel and valvetrain details rather than a stage label alone.
Why isn't Corvette generation alone enough to choose a tune?
The actual engine, controller, transmission and installed parts identify the tuning job. Use the builder's exact application choices and tell JRJ about conversions or changes since the car left the factory.
Can I use an LS3 Camaro file for an LS3 Corvette?
The shared engine name is not a whole-vehicle compatibility check. JRJ remote tuning starts with your Corvette's own read; downloaded reference files require their separate listed checks.
What should I tell Jason about the drivetrain?
Provide the installed transmission, clutch or converter, rear gearing and tire size. Describe the conditions you want reviewed, such as pulling away, low-speed driving or shifting, and include those observations with the requested logs for Full Custom.
Which service includes ongoing datalog review?
Full Custom includes datalog review and up to five revisions. Base is a starting tune with two revisions for startup, idle and initial drivability.
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.
