Need adjustments after changes to your setup? This service is for existing customers who’ve already received a full custom tune and need updates due to new mods, different fuel, or drivability tweaks.
What’s Included:
-
Calibration updates for existing customers
Support for changes such as:
-
New fuel type (e.g. pump gas to E85)
-
Upgraded parts (injectors, MAF, intake, etc.)
-
Drivability improvements or corrections
-
-
Data review and fine-tuning (dyno or street-based depending on service type)
Requirements:
-
Must be an existing tuning customer
-
Vehicle must still be using the same ECU and platform as originally tuned
-
Any major changes (e.g. added boost, nitrous, or meth injection) will require purchasing the Boost/Nitrous/Meth Add-On separately
-
Appointment required
Common Scenarios for Retuning:
-
Switching fuel type (91 > 93, 93 > E85)
-
Upgraded injectors or fuel system
-
Intake/exhaust changes
-
Transmission changes
-
General performance adjustments
Important Notes:
-
This is not for completely new builds or engine swaps — please book a full EFI Engine Tuning Service for that
-
All vehicles must be mechanically sound and ready for tuning
-
Additional dyno time or labor may result in extra charges if significant changes are found outside of the original scope
