Base Tune — Stock Truck

Ideal for a completely stock LV3 or lightly modified setup — cold air intake, headers, exhaust. Cleans up GM's lazy factory calibration, sharpens throttle response, smooths shifting, and improves overall drivability.

Cam Tune

Built for LV3 engines running a DOD/AFM delete and an aftermarket cam. Corrects airflow, fueling, idle control, and stalling issues while keeping an aggressive, controlled cam chop. Works with a wide range of popular cam options — see below.

Supported Cam Options

We build the cam tune around your specific camshaft. Message us with your cam details before or after purchase so we can dial it in correctly for your setup. Popular options include:

BTR Stage 2 GEN V LV3 Truck Cam
BTR Stage 3 GEN V LV3 Truck Cam
Texas Speed Street / Performance Cams
Comp Cams LV3 options
Other aftermarket LV3-compatible camshafts — ask us if you don't see yours listed

⚠️ Flashing & Safety Notice

Flashing your PCM can be dangerous if not done properly. Follow these steps to avoid bricking your PCM:

Never flash over Bluetooth or Wi-Fi — always use a hard-wired USB connection
Connect a battery charger to maintain stable voltage during the write process
Do not interrupt the process once writing has begun

J.R. Jones Automotive & Performance is not liable for any PCM or ECU damage resulting from improper flashing or unsafe tuning practices.
