Harley-Davidson tuning at Rapid Racing

We support 79 Harley-Davidson vehicles across 44 models, covering model years 2013+, through AutoTuner and HP Tuners. That includes gasoline powertrains and 6 engine and transmission controllers.

Each Harley-Davidson tune is calibrated for your exact hardware and fuel, then verified with real data on our Dynojet 424xLC2 in Jenison, MI, serving Grand Rapids and West Michigan. 37 of these Harley-Davidson applications also support remote tuning, so you can flash and datalog from anywhere.
