Harley-Davidson Twin Cam (2001–2017) Custom Bench Flash Tuning – Delphi ECU (88 / 96 / 103 / 110 Engines)

Our custom bench-flash calibrations for the Harley-Davidson Twin Cam era (2001–2017) unlock hidden performance from the Delphi EFI system. Using KESS3 bench flashing and WinOLS binary editing, we go far beyond canned “download” maps. Each tune is tailored to your exact setup, with precise control over fuel, spark, idle, throttle response, rev limits, and torque management. The result: smoother cruising, stronger mid-range torque, and more horsepower across the entire RPM range.
