Frequently Asked Questions
Answers for common fitment, installation, and support questions.
Aftermarket calibration can affect warranty coverage and service decisions. Terms and laws vary, so review your warranty and speak with the provider before modifying the vehicle. Returning an ECU to a stock file does not guarantee that prior changes are undetectable.
Depending on the ECU and vehicle, the available path may be remote flashing, an in-shop appointment, or a bench/unlock service. The required hardware and timing are confirmed during vehicle review.
Stock-file restoration is available on supported ECUs. We confirm how the original calibration is handled, any unlock implications, and the restoration path for your specific vehicle before purchase. Restoration does not guarantee that prior changes are undetectable.
Timing depends on the ECU, required unlock work, current hardware, and whether the job is remote or in-shop. The installation window and any optional dyno time are confirmed during vehicle review.
We offer custom calibrations for modified vehicles. Contact us with your mod list and we'll build a tune matched to your setup.
