Common Questions

What types of vehicles do you work on?

DD84 reviews supported GM, Ford, Dodge/Hemi, Toyota/Lexus and aftermarket EFI applications case by case. Send the year, make, model, engine, controller, modifications and goal before buying a tune or booking a service.

How long does the tuning process take?

Timing depends on the controller, file access, vehicle readiness, the quality of submitted data logs and the number of revisions needed. DD84 confirms the service scope and expected turnaround after reviewing your setup; do not assume same-day delivery.

What support comes with a tune?

The service or product listing and written quote define its scope, revisions and support. If an issue comes up, contact DD84 with the order details and current data logs so we can review the next step. Vehicle condition and later hardware changes can affect the result.
