About DiabloSport

DiabloSport is a manufacturer of high performance automotive electronics that re-program a vehicle’s factory computer. We are an industry leader in vehicle calibration, which is performed by “flashing” or re-programming vehicles through the OBD-II port (Diagnostics port).

Since 2001, DiabloSport offers industry leading performance programmers that stay ahead of the technology curves. Today, we are the only company to offer color touch screen hand-held programmers in all of our OBD-II flash devices. Our 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.

We are horsepower junkies by trade- making the biggest possible power gain is why we come to work every day. If you feel the same way about your vehicle’s performance, you are in the right place. We use an in-ground Super Flow Chassis dyno to make develop our performance tunes, and then we take the cars out on the Florida streets to see what they have. We will not settle for anything but the maximum horsepower and torque gains over stock!
