Rojo Motorsports the leader in tuning technology for medium & heavy-duty trucks. Our team has a combined 15+ years of true hands-on factory OEM experience. What does this mean for you? It means our tuning is SAFE, RELIABLE & most importantly it’s been PROVEN to work in the real world by real customers. We take great pride in knowing our customers are getting what they need & want out their trucks, without sacrificing any of the important stuff like fuel economy, on board diagnostics, or pre-set safety points within the engine operating parameters. Unlike some of our competitor’s we don’t use trickery to fool the computer into doing what we want it to do, we can simply tell it how to run the truck.
