This tune file is built for 2007-2013 GM LS truck and SUV platforms using the 4.8L, 5.3L, 6.0L, or 6.2L engine family.
If you have a BTR Truck Norris, Texas Speed Chopacabra, or similar LS truck cam in one of these trucks or SUVs, this tune will work for you. It also works for stock and bolt-on trucks that need a clean, corrected calibration.
Your tune is built around your factory read file, operating system, engine size, transmission, cam setup, and full modification list. Most setups take 3-5 revisions, and we finish the tune instead of leaving you stuck after one file.
The 2007-2013 GM truck platform covers a huge range of Gen IV LS combinations. Whether your truck is stock, bolt-on, or cammed, the calibration needs to match the engine, transmission, DOD/AFM setup, airflow model, fuel system, and actual parts on the truck.
These vehicles share the 2007-2013 GM truck/SUV LS platform family when equipped with supported 4.8L, 5.3L, 6.0L, or 6.2L engine combinations.
This is a performance calibration designed for GM LS trucks and SUVs running stock, bolt-on, or cammed setups with 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 Silverado, Sierra, Tahoe, Yukon, Suburban, Avalanche, Escalade, or Hummer H2 has injectors, converter changes, gear/tire changes, boost, nitrous, or anything beyond a normal stock / Truck Norris / Chopacabra style setup, use the Build Your Tune page so we can match the calibration to your exact vehicle.
