DiabloSport is an industry-leading manufacturer of automotive performance programmers based in Sanford, Florida. They focus on making the maximum power, drivability, and fuel economy gain on late model fuel injected vehicles. Whether gas or diesel powered, our products optimize a vehicle?s performance by programming its factory computer or plugging it into its factory engine harness. Since 2001, DiabloSport offers industry-leading performance programmers that stay ahead of the technology curves. Today, they are the only company to offer color touch screen hand-held programmers in all of their OBD-II flash devices. Their goal is to continue offering innovative electronics that are loaded with industry-leading ?tune? files that create better power, economy, and drivability on late model cars and trucks
DiabloSport is made up of a team of people who are horsepower junkies by trade- making the biggest possible power gain is why they go to work every day. They use an in-ground SuperFlow Chassis dyno to make and develop their performance tunes, and then they take the cars out on the Florida streets to see what they have. DiabloSport will not settle for anything but the maximum horsepower and torque gains over stock. DiabloSport is a manufacturer of high-performance automotive electronics that re-program a vehicle?s factory computer. They are an industry leader in vehicle calibration, which is performed by ?flashing? or re-programming vehicles through the OBD-II port (Diagnostics port).
