Before you get started
A few common questions.
Can you help if I’m outside San Antonio?
Remote tuning inquiries are welcome. Available services depend on your vehicle, tuning device, and setup. Send those details in your request so compatibility can be reviewed.
Which tuning device do I need?
C&D works with EZ LYNK, EFILive, and HP Tuners. The correct platform depends on the vehicle and service. Ask before purchasing a device or license.
How much does tuning cost?
Use the tuning selector for listed 2010–2024 Ram EFILive, EZ LYNK, and HP Tuners packages. Pricing for other vehicles is quoted individually. Device requirements, licensing, and the scope of work are confirmed before payment.
Can I request help with an existing tune?
Yes. Choose Custom tune consultation and describe the concern, your current device, and any modifications. An inquiry does not guarantee a specific fix; the setup needs to be reviewed first.
