Get the right technical path for your vehicle
We review the vehicle, controller, modifications, symptoms and goals before recommending a tuning, diagnostic, programming or build service. DD84 is based in Jefferson, Georgia, with remote support for compatible platforms.
What to include in your request
Vehicle and controller
Year, make, model, engine, transmission, VIN when requested, and ECU/PCM or standalone system details if known.
Current setup
Fuel, injectors, power adders, camshaft, wiring changes, hardware and software access, existing calibration and any available logs.
Problem and goal
Symptoms, diagnostic codes, recent repairs, mechanical condition, intended use, location and the result you want.
Before scheduling work
DD84 confirms compatibility, file or module access, required hardware, vehicle readiness and the proposed scope. Unsafe conditions, leaks, overheating or unresolved faults may need repair first. Local or mobile availability is confirmed for each request; an inquiry is not a confirmed appointment.
