Frequently Asked Questions

How Long Does the Tune Take?admin2025-09-10T02:08:10+00:00

How Long Does the Tune Take?

The tuning process typically takes 20-30 minutes for our base calibrations. Supercharged and/or Custom Calibrations can take upwards of 1-2 hours, depending on vehicle modifications.

Will This Void My Warranty?admin2025-09-10T02:08:32+00:00

Like any aftermarket part or modification, the tune can potentially void your vehicle’s warranty IF the dealer can prove it directly caused the issue. Currently, there have been no reported issues or warranty problems related to OTT tunes across multiple platforms. With tens of thousands of trucks across the country with OTT, we haven’t experienced any warranty issues.

Can the Dealer Detect The Tune?admin2025-09-10T02:09:02+00:00

Can the Dealer Detect The Tune?

Your vehicle’s ECU ID will remain stock, and the calibrations are native to the ECU. The CVN number is updated after the ECU has been modified. Your vehicle will be treated no differently than stock, and all diagnostic and dealership functions will remain the same.

And thanks to the Magnuson-Moss Warranty Act, your factory warranty cannot be voided just because you’ve tuned your ECU. A dealer would need to prove that the tune directly caused a specific issue before denying warranty coverage.

Can I Go Back to the Stock Tune?admin2025-09-10T02:09:26+00:00

Can I Go Back to the Stock Tune?

Yes, it’s a simple process to flash the stock calibration back on the vehicle.

Will the Tune Correct My Speedometer for Larger Tires?admin2025-09-10T02:09:55+00:00

Will the Tune Correct My Speedometer for Larger Tires?

No, unfortunately, the tune cannot calibrate the speedometer. You will need to purchase a speedometer calibrator to adjust accordingly.

Can My Vehicle be Tuned if the Catalytic Converters Have Been Removed or if There is a CEL?admin2025-09-10T02:11:12+00:00

Can My Vehicle be Tuned if the Catalytic Converters Have Been Removed or if There is a CEL?

All emission components must be fully intact for the vehicle to be tuned. Additionally, any CEL’s need to be addressed and resolved prior to getting tuned.

“Marty tuned my 2020 supercharged Tundra with the OTT tune and man what an incredible experience. I highly recommend working with Marty and if you’re debating on getting the tune, don’t! One of the best mods I’ve ever done. I went with the medium/spicy and what a difference it makes. Fast efficient and professional. What more can you ask for.”

“This was the best thing I have done for the performance of my Toyota Tacoma. The truck is more responsive and just runs better. I didn’t think that it was possible for it to run this great. The power seems limitless and that really makes it seem to just be smoother
Marty is A++ with his knowledge of Toyota vehicles. He was quick to get me scheduled and waiting on me when I got there once I got there the service was quick and didn’t waste my time nor his time.”

“Just trusted ATO Tuning with putting the Overland Tailor Tuning (OTT) tune on my 2024 Toyota Tacoma TRD Offroad and EXTREMELY HAPPY with the results. Everything went as described and didn’t take long, I’m driving a new truck for sure. I would trust ATO Tuning for all you vehicle tuning needs!! Highly Recommend!!”

“I couldn’t be happier with my OTT tune Marty put on my 2017 Tacoma. With the 5.29 gears paired with the gear specific tune and light throttle option, it’s a night and day difference from stock! No more gear hunting, cruise control works great now, and it’s much more responsive! Definitely recommend ATO tuning for your Toyota tuning needs”
