Professional Holley EFI Tuning for Street and Performance Builds
Choose the package that matches your naturally aspirated, cammed, E85, flex-fuel, or boosted combination. DD84 provides custom Holley EFI calibration support focused on reliable startup, idle quality, drivability, fueling, ignition strategy, and safe system operation.
Service Packages
- Startup Calibration File Only: Initial ECU configuration to start and idle a mechanically complete vehicle. This is not a finished street tune.

- Remote Cammed/Modified NA Tune: For camshaft, injector, intake, exhaust, and other airflow modifications.

- In-Person Boosted Street Tune: For turbocharged or supercharged street combinations after fuel-system and mechanical verification.
Before Tuning
The vehicle must have correct wiring, stable fuel pressure, verified sensors, no mechanical faults, and a safe operating condition. Additional troubleshooting, wiring repair, travel, dyno time, advanced boost control, nitrous strategy, or transmission work may require a separate quote.
