Will tuning void my factory warranty?

A tune can affect powertrain warranty coverage. We are upfront about it: we will tell you what is at risk on your specific platform, and on most vehicles we can return the car to a stock file if you need it back to factory calibration for a dealer visit.

Is a tuned car still reliable?

That is the whole point of a custom calibration. We tune around your hardware, fuel and driving conditions with safe knock, boost and temperature targets, rather than loading a generic file written for someone else's car.

How long does it take?

Most ECU-only tunes are a same-day appointment. Stage kits and hardware installs typically run one to three days depending on parts availability. We confirm the timeline before you book.

Tune pricing depends on platform and stage, so we quote per vehicle. Our published shop labor rate is $180/hr. Send your car details through the form and we come back with a real number.

Do you work on cars you didn't build?

Yes. Modified cars, other shops' tunes and problem builds are a large part of what we do. Tell us what has been done to it in the form and we will pick it up from there.

Where are you and who do you serve?

We are at 1360 Union Hill Rd, Suite 10A in Alpharetta, and we serve the whole Metro Atlanta area including Roswell, Sandy Springs, Marietta, Johns Creek and Dunwoody.
