In-Person Tuning FAQ
What is in-person OTT tuning?
In-person OTT tuning is a one-on-one appointment where we install an Overland Tailor Tuning (OTT) calibration on your Toyota or Lexus and dial it in on the spot. You get sharper throttle response, smoother shifting, and a more refined drive, tuned to the way you actually drive.
What is included in an appointment?
We load your OTT tune, update your vehicle to the latest ECU software from Toyota or Lexus at no extra charge, and make sure everything is running the way it should before you leave. If you have questions about your setup, this is a great time to ask.
How long does an in-person tuning appointment take?
Most appointments take about 15 to 30 minutes. The exact time depends on your vehicle, your customization requests, and the calibration type, but you will not be waiting around all day.
Do I need to update my ECU software before my appointment?
No. Skip the dealership trip. As part of our service we update your vehicle with the latest ECU software update from Toyota or Lexus for free. This is what we mean when we refer to a TSB, or Technical Service Bulletin.
Where do in-person tuning appointments take place?
Tuning can be done mobile with prior planning or at a set location. Once your appointment is booked, you will receive the exact address and details in your confirmation email.
How do I book an in-person tuning appointment?
Choose your appointment option and select an available time, or reach out to us directly. We will confirm your date, time, and everything you need to know before you arrive.
Will tuning void my warranty, and can the dealer still service my vehicle?
A tune is like any aftermarket part. Your dealer would have to prove the tune directly caused a specific failure to deny that item under warranty, and we make no guarantees either way. Many of our customers visit their dealership with no issues, the dealer can still run diagnostics and service your vehicle normally.
Can my vehicle be put back to stock?
Yes. Whether you were tuned in person, with a pre-tuned ECU, or with a COBB Accessport V3, we can always return your vehicle to stock.
What areas do you serve for in-person tuning?
We serve Middle Tennessee and Western Kentucky, with regular appointments in the Nashville area and rotating visits to Knoxville and Chattanooga. As an authorized OTT retailer, we have tuned Toyota and Lexus vehicles across the region since 2021.
