For GM, Ford and Dodge owners, DIY tuners and shops seeking a second opinion on an existing ECU calibration. DD84 reviews the supplied file and vehicle information and provides written findings and recommendations.
Choose the review scope
- Basic File Review: review of the supplied calibration file.
- File Review + Datalog Review: calibration and supplied compatible datalog review.
- Priority File Review: priority scheduling subject to DD84 confirming availability; request the turnaround before purchase.
Review may cover airflow, fueling, spark, idle and drivability concerns where supported. Findings depend on the information supplied; a file review cannot certify the vehicle's mechanical condition.
Before purchase
Send the vehicle year, make, model, engine, transmission, controller/software, modifications, fuel, symptoms and available files through DD84 intake. DD84 confirms file compatibility and the appropriate review scope.
Not included: editing or delivering a tune, flashing, tune revisions, credits/licensing, unlocks or physical repairs. Any additional work is scoped and quoted separately. If you only need to check whether a vehicle is ready for a future tune, ask about the separate tune-readiness review.
Unresolved mechanical, electrical or fuel-system faults must be addressed before performance calibration. Contact: downdirty84llc@gmail.com.
