Your selected vehicle, engine, cam and add-ons use the same pricing as the main tune builder. Your verified fixed credit is subtracted from the tune price. The exact amount, plus any tax and equipment shipping, is shown before payment.
Use an HP Tuners MPVI2, MPVI3 or MPVI4 supported for your vehicle. JRJ does not currently support RTD or TDN devices. You can add an MPVI4 under Equipment; vehicle credits are sold separately. Check device requirements.
Just select year, make, model, and cam to see your tuning options.
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.
This add-on covers the extra troubleshooting involved when changing engine and computer generations. Enter the vehicle the engine and PCM are going into below.
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.
Supporting every possible vehicle, cam, and modification combination would require more than 14,000 separate files, so modification support is not currently offered with downloadable files. 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 exact product page to review its description and compatibility, confirm all seven requirements, and add it to your cart.
No closest file will be substituted. Choose a tune built from your own vehicle file instead.

Remote tuning has to be done one step at a time. It is not always as simple as sending one file and being finished. A lot of things can affect how fast the process goes: the condition of the vehicle, mechanical issues, whether the data log shows the issues, how many modifications the vehicle has, how quickly we can communicate back and forth, my current workload, and any unexpected problems we run into along the way.
Please read the complete remote tuning checklist and process before you begin. We have to work forward one step at a time. That has proven to be the safest and most efficient way to do this. If we skip steps or try to change too many things at once, it can slow everything down and make us work backward.
