Full Custom Remote Tune
Built from your stock read and submitted build details, with private Tune Portal delivery, datalog review, and revision support.
Build Custom TuneSearch the GM LS, GM LT, EcoTec3, and Mopar HEMI combinations currently mapped in the J.R. Jones Racing LLC tune builder. Every vehicle route below is connected to its engine-specific cam catalog.
Open a platform to see every make and model entry, each supported engine route, and the cam catalog that engine uses. Search also understands cam names, engine codes, and model variants.
The builder remains the final source of truth. A model appearing here does not mean every engine, controller, operating system, security configuration, modification, or tune type is supported. Never choose the closest vehicle just to force a match.
Cam names are not dumped into one universal list. Cathedral-port LS, rectangle-port LS, Gen V LT/EcoTec3, 5.7 VVT HEMI, 6.1 non-VVT HEMI, 6.4 VVT HEMI, and supercharged 6.2 HEMI combinations stay separated.
Catalog support is not a mechanical fitment guarantee. Piston-to-valve clearance, spring requirements, phaser limits, DOD/AFM/MDS hardware, VVT hardware, converter, compression, fuel system, and intended use must be verified for the actual build.
The same vehicle and cam can require a different service depending on the rest of the build and how much calibration support is needed.

Build Custom TuneBuilt from your stock read for startup, idle, and initial drivability. It does not replace the refinement available with the full custom path.
Choose Base TunePrewritten Compare & Copy reference file for an exact supported match. No custom modification support, datalog review, or remote revisions are included.
Search Download FilesThese checks protect the vehicle and keep the order connected to the correct tune product, calibration file, and support path.
Use HP Tuners MPVI2, MPVI3, MPVI4, or a supported EFI Live workflow with the required licensing or credits. RTD/TDN devices are not supported. Keep the vehicle’s original stock read.
Provide the real year, make, model, engine code, transmission, drivetrain, VIN, controller, and operating system when requested. Overlap years can resolve to different products.
Provide the cam card or complete intake duration, exhaust duration, lift, and LSA when the cam is not listed. Include delete hardware, heads, induction, fuel, converter, gearing, tires, and forced induction.
A tune cannot repair bad sensors, weak fuel delivery, wiring faults, exhaust leaks, mechanical damage, missing hardware, or an unfinished cam swap. Diagnose and complete the vehicle first.
Use these answers with the catalog above, then let the live builder resolve the final product and starting price.
No. Each cam is shown inside an engine-specific catalog. The vehicle platform and exact engine determine which catalog is available, and mechanical fitment still must be verified for the actual build.
Choose “Cam Not Listed - Enter Cam Specs” in the tune builder and provide the full cam card or complete intake duration, exhaust duration, lift, and LSA. Do not choose a similar cam name.
No. Downloadable .HPT files require an exact supported match and do not include changes for headers, blowers, injectors, intake manifolds, heads, converters, transmissions, gears, tire size, fuel systems, or other add-ons. Use Base or Full Custom Remote Tuning for supported modified combinations.
The same model name can use different engines, controllers, operating systems, airflow strategies, fuel systems, transmission logic, and security requirements. Those details can change the correct product and calibration path.
Have the exact year, make, model, engine, transmission, drivetrain, original stock read, device type, cam card, delete and VVT hardware details, fuel type, converter, gearing, tire size, induction, exhaust, injector, and forced-induction information ready.
HP Tuners MPVI2, MPVI3, MPVI4, and supported EFI Live workflows are accepted when the required licensing or credits are available. RTD/TDN devices are not supported.
Select the real vehicle, engine, camshaft, transmission, drivetrain, tune type, and modifications. The live builder will resolve the correct product and starting price before anything is added to the cart.
