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?
Provide the cam card, engine, fuel, injectors, intake, exhaust and drivetrain details. Tell Jason what matters in everyday use, such as startup, in-gear idle and low-speed response, rather than using idle sound as the only goal.
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
Send the manufacturer, exact cam part number and cam card. Include the installed converter or clutch and explain how you use the vehicle, so startup, in-gear idle and everyday driving can be discussed with the correct setup.
Choose the named cam offered for your vehicle and engine. If you use the add-your-own-cam option, enter the actual cam-card values requested by the builder. A Stage 2 label alone is not a substitute for the manufacturer, part number and specifications.
Straight answers
Stage 2 Cam tuning questions
Is a Stage 2 download the same product?
No. A downloadable .HPT file is a separate product with its own listed application and usage requirements. Review its file details before purchase. Remote tuning and modification add-ons are separate.
Does every Stage 2 cam need the same converter?
Follow the requirements for your exact cam part number, and give JRJ the installed transmission and converter details. Texas Speed lists different converter requirements for its LS3 and L92 Stage 2 cams, so the stage name alone is not enough.
Are all Stage 2 cams priced and tuned the same?
The builder uses the actual supported cam and engine mapping. A Stage 2 name by itself is not enough to identify the service charge or the work required.
Is Stage 2 included in the $169.99 Base Tune price?
Base includes the standard cam tuning charge. Applicable higher-stage charges, including Stage 2, are additional and appear in the itemized breakdown.
Can I enter a cam that is not named in the list?
Use the add-your-own-cam option when available and enter the requested cam-card specifications. Do not substitute a similar named cam just to obtain a price.
Why choose Full Custom for a Stage 2 build?
Full Custom includes datalog review and up to five revisions for supported refinement. Base is a more limited startup, idle and initial-drivability service with two revisions.
