Answers for common fitment, installation, and support questions.

Yes. Every Gintani tune is fully reversible. We store your factory calibration and can restore it at any time.
Remote installs typically take 30–45 minutes. In-shop appointments are usually same-day, with optional dyno time available when the build calls for it.
We offer custom calibrations for modified vehicles. Contact us with your mod list and we'll build a tune matched to your setup.
