LS & HEMI
Tune Files
That Work

JR Jones Racing builds HP Tuners / EFI Live remote tune files for LS and HEMI cam swaps, including Texas Speed Chopacabra, BTR Truck Norris, Sloppy Mechanics, stock bolt-on setups, and DOD / AFM delete tunes. This is a real tuning experience, not a generic file you buy and hope for the best. Upload your stock read file and vehicle details, then we use feedback, data logs, and revisions to dial in the calibration for your exact truck, SUV, or performance car.

Use The Current Tuning Software

Please make sure you have the most current version of HP Tuners VCM Suite or EFI Live before reading, flashing, or sending files. If you do not have it yet, download it here.

Before Tuning Starts

Be Ready For The Real Process

No two vehicles are the same. Mileage, age, condition, fuel system, exhaust, sensors, wiring, grounds, camshaft, converter, gear ratio, and overall setup all affect what the calibration needs.

JR Jones Racing starts with your stock read file, writes the base tune, then relies on your feedback and data logging to dial it in. Your build needs to be complete and ready to tune before we start.

Texas Speed Customer Trust

Texas Speed Cam Customers Keep Finding Us

We are hearing the same thing again and again: customers buying Texas Speed parts are being pointed our direction when they need the tune side handled right. If you already bought a Texas Speed cam and need the file to match it, you are in the right place.

Chopacabra One of the most common Texas Speed truck cam setups we help customers with.
Built To Match We pair the tune to your actual cam, platform, bolt-ons, injectors, and goals.
Real Support Questions, revisions, and help after the file is delivered instead of just sending you on your way.
What Customers Keep Telling Us
"I bought my parts from Texas Speed, and when it came time to get the tune handled, your name kept coming up."
That is exactly why we built this side of the business: parts are only half the combo. The tune is what makes the setup work the way it should.

Built By A Real Gearhead

Jason Jones is a Wilmington, NC native, GM LS specialist, and the one-man operator behind JR Jones Racing. What started as real cam swap, DOD delete, and tuning work turned into a business built around helping customers get the right file, parts, and support without the runaround.

The YouTube channel helped customers get to know the work first, and that trust is what pushed the store, the portal, and the systems behind the business. The full story, including the software and tech side of what Jason builds, lives on the About page.

Bro, 20 stars. Did a Chopacabra cam setup on 37s with 4.56 rear gears. They did everything and were super responsive.

Fixed every issue I had. 10 out of 10. If you need something as close to perfect as possible, this is the place.
