Optional Calibrator Tool Rental

The actuator will require calibration to complete the re-installation. We can include an optional calibration tool in the shipment of your actuator for an additional rental fee of $100. This calibration tool allows you to accomplish the entire installation process without a trip to the dealer or mechanic. Additionally, unlike other calibration procedures, our calibration tool will not require any changes to your custom tune.

Note: There will be an additional charge of $500 if the calibration tool is NOT returned to us within 15 calendar days of the shipment of this product.

We do not require an up front core deposit, but a core charge must be captured if a rebuildable turbo actuator is not returned to Circuit Board Medics. If your core is not received within 15 calendar days, an additional core charge of $350 will be charged to your credit card.

    • No prior repair attempts
