This is a pre-written performance tune file built for 1998–2002 Chevrolet Camaro 5.7L LS1 cars running the Texas Speed TSP 220R camshaft or a similar 220/220 cam profile.
Designed around the popular 220/220, .600"/.600", 112 LSA LS1 camshaft setup, this calibration is built for real street performance — clean idle control, corrected airflow, improved fueling, stronger throttle response, and smooth drivability with an aggressive LS1 attitude.
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.
The Texas Speed 220R is a proven LS1 street performance cam, but it still needs the tune handled correctly. Stock-style calibrations usually struggle with idle instability, cold start issues, incorrect airflow, poor low-speed manners, and fuel trims that do not match the new camshaft airflow demand.
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.
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.
If your Camaro has injectors, boost, nitrous, converter changes, gear/tire changes, engine swap details, or anything beyond a basic TSP 220R cammed LS1 build, use the Build Your Tune page so we can match the calibration to your exact vehicle.
