BTR Stage 2 V2 Cam Tune File
This is a custom remote tune built for 1998–2002 Chevrolet Camaro 5.7L LS1 cars running the BTR LS1/LS2 Stage 2 V2 camshaft or a similar street performance cam setup.
Designed around the popular 225/23X, .615"/.636", 113 LSA Brian Tooley Racing camshaft, this calibration is built for real cammed LS drivability — stable idle control, corrected airflow, cleaner fueling, sharper throttle response, and strong midrange/top-end power.
This is not a random pulled file. Your tune is built around your factory read file, operating system, engine, transmission, injector data, cam setup, and full modification list.
BTR Stage 2 V2 LS1 Tune Built for Real Street Driving
The BTR Stage 2 V2 camshaft is a strong street/strip LS1 cam, but it needs the tune handled correctly. Stock-style calibrations usually struggle with idle surge, hanging RPM, poor cold starts, bucking, incorrect airflow modeling, and fuel trims that no longer match the new camshaft airflow demand.
- Built specifically for 1998–2002 Camaro LS1 platforms
- Designed around BTR LS1/LS2 Stage 2 V2 camshaft setups
- Corrects idle airflow, spark, fueling, throttle response, and drivability
- Supports common bolt-ons like headers, cold air intake, exhaust, and intake manifold upgrades
- Built from your actual factory read file — not a one-size-fits-all upload
- Available for HP Tuners users

Performance & Build Responsibility Notice
This is not a stock tune. This is a performance calibration designed for modified vehicles running a camshaft and supporting parts.
You are responsible for making sure your build quality is up to par before flashing or running this tune. Your engine, valvetrain, fuel system, drivetrain, wiring, sensors, injectors, exhaust, and all supporting parts must be correctly installed, mechanically sound, and capable of handling increased performance.
Poor installation, worn parts, incorrect valve spring setup, wrong pushrod length, weak fuel supply, vacuum leaks, exhaust leaks, bad sensors, or unsafe mechanical condition can cause drivability issues or engine damage that no tune can fix.
J.R. Jones Automotive & Performance is not liable for engine failure, drivetrain damage, PCM/ECU damage, or any issue caused by poor build quality, improper installation, unsafe flashing practices, incorrect customer-supplied information, or misuse of this tune.
Flashing Safety Notice
Always flash using a hard-wired USB connection. Do not flash over weak connections, unstable power, or while the vehicle battery is low.
Use a battery charger or maintainer during the write process. Do not interrupt the flash once writing has started.
Customer is responsible for having the proper tuning hardware, software, licensing, and stable equipment needed to read and flash the vehicle.
Have More Changes to Your Build?
If your Camaro has injectors, boost, nitrous, converter changes, gear/tire changes, engine swap details, or anything beyond a basic BTR Stage 2 V2 cammed LS1 build, use the Build Your Tune page so we can match the calibration to your exact vehicle.
