Existing Customer Re-Tune

Existing Customer Re-Tune

This service is for customers who previously completed a Yosh Tuned calibration and have since changed something that affects the tune.

This is not for vehicles previously tuned by another tuner. If Yosh Tuned did not complete your previous calibration, purchase the appropriate full e-tuning service instead.

Use This Service If You Changed

• Injectors or fuel pressure
• Fuel type or ethanol content
• MAP sensor or wideband configuration
• Intake, manifold, throttle body, header, or exhaust
• Camshafts or internal engine components
• Turbocharger, supercharger, pulley, or boost level
• Fuel-system components or other major calibration-related hardware

Before You Buy

• You must be an existing Yosh Tuned customer with a previously completed calibration.
• Have your previous order number and latest Yosh Tuned calibration available.
• Your vehicle must be mechanically sound and ready to tune.
• Tuning services must be started within 30 days of purchase unless Yosh Tuned approves otherwise.
• If you are unsure whether your changes require a Re-Tune, contact tuning@yoshtuned.com before purchasing.

What’s Included

• Calibration adjustments for the new setup covered by this service
• Datalog review and revisions as needed
• Final updated calibration after the re-tuning process is completed
• Email guidance throughout the process
