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.
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.
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.
Pick your platform, engine, cam, a few common mods, and whether you need an HP Tuners device. Then jump straight to review and checkout.
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.

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.
Cam swaps, DOD delete work, tuning walkthroughs, and the real shop content that helped grow JR Jones Racing in the first place.

Real feedback from customers running JR Jones Racing tune files, cam swaps, Chopacabra setups, LS builds, and HEMI performance calibrations.
Tuned my 2004 Z71 with a Chopacabra cam, cold air intake, and long tubes perfectly. The truck has a good chop, strong performance, and drives exactly like it should.
The amount of care he shows his customers is beyond perfect. You can tell he actually cares about getting it right.
Great experience from start to finish. Couldn't have asked for a better outcome.
Highly recommend him for automotive tuning needs and repairs. Timely service, punctuality, honesty, and integrity.
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.
Great guy. Good example of an honest mechanic and tuner that knows his job.
Highly recommend. I'll be using him again.
I normally don't leave reviews, but I was so pleased with this place I had to share. I replaced the cam and lifters in my 2011 Ram 1500 and went with the Chopacabra from Texas Speed and Mopar lifters.
After the cam swap, I needed help tuning and found Jason through YouTube. I sent him my factory tune file, purchased the pre-written tune file, and he started communicating right away.
Great prices, excellent work, and the truck runs great.
