Precision Calibration.
Peak Performance. maximum safety.
Rios Racing.
With a passion for making horsepower, Mark started building and tuning LS vehicles back in 2010 when he was on active duty in the US Army working on UH60 Blackhawk helicopters. Over the next 7 years, with just evenings, weekends, and around deployments, he built a reputation out of a 2-car garage in rural North Carolina, which would grow into a name with international recognition in late model GM performance with customers as far as France, UAE, Australia, and Canada.
Now, with over 15 years of experience on the LS and Gen5 LT platform, we have developed the knowledge base, network, and practices required to help meet your goals and exceed expectations. In short, we’ve done the research, testing, trial, and error so you don’t have to.
While we pride ourselves on quality and will be the first to tell you that “We are not the cheapest, and we may not have the fastest turnaround times, but it will be right when it’s done,” I also spend your money like it’s mine. Meaning: You can rest assured knowing we won’t ever try to sell you anything you don’t need, we do not take shortcuts, and I will be 100% honest with you.
Whether you have a bone stock daily driver, rowdy weekend warrior, drift car, 1500hp daily or 1800hp drag and drive car, stock, or aftermarket ecu, we will calibrate it with precision, get all the power it has to offer, while taking the necessary steps to protect your investment with advanced safety features that give you piece of mind when ripping on it.

Why do you need a custom calibration?
Simple! A custom tune from a quality calibrator is what brings the whole ride together. You can spend the best money on the best parts, on the most well-planned-out combo in the world. . . . but if the tune isn’t spot on, then performance, safety, drivability, and longevity all suffer
