Overland Tailor Tuning (OTT) is one of the few companies in the Toyota world to provide dyno data for the platforms we support. We also strive to help educate the public about the R&D we perform when testing/validating parts. OTT has an entire thread dedicated to the 2nd Gen Tacoma 4.0L sharing our dyno data and parts testing results – aiming to help guide and allow all owners to make informed decisions about their parts choices. We do this at no cost to the end-user and provide free data to the masses. 

Regarding the tuning, you’ll often hear competitors say, “we all use the same software to tune the vehicle”. This is being done to try and justify putting other products on a level playing field with us. While there is some truth to that statement, critical components or facets of the process are also glossed over with that philosophy. The core component of what makes OTT a standout within the Toyota tuning industry is the experience we bring to the plate. We have a collective 30+ years of tuning EFI systems, including transplanting OBD-equipped engines from one manufacturer to another chassis. Our understanding of the systems we’re developing gives us a unique perspective on approaching a problem. We often evaluate and look at calibrating on a system or component level, not just how something feels in seat-of-the-pants testing. 

Another significant area that sets us apart is how we derive the data we ultimately use and how the calibration is developed, bringing the ECM/TCM tuning together in synchrony. All our changes are modeled using proprietary software & methods that have been developed in-house. This modeling goes above and beyond simply editing the existing values in the OE calibration. We often restructure/reformat how the data is referenced in the calibrations, allowing us to fix specific areas of the OE calibration that would not be possible by simply adding, subtracting, or multiplying the original map/table like most others. 

Our testing goes beyond increased power figures or enhanced driving experience as we also invest heavily in R&D to ensure our calibrations are not gross polluters. We utilize our in-house 5-gas analyzer to preliminary evaluate our calibrations using specialized software and the dyno to simulate the drive cycles required for emissions certification. In fact, our 3rd Gen Tacoma 3.5L calibration just recently achieved its SEMA Certified Emissions classification and is currently underway to achieve CARB approval. 

Your Toyota vehicle is too important to trust to just anyone, trust OTT and Compromise elsewhere.

First, we’ll ask that you give us your truck’s details and sign a waiver giving us the okay to tune your truck. We’ll start by identifying your specific needs and preferences to select the proper tune for your vehicle. We then connect a battery power supply to maintain proper battery voltage to your vehicle while we perform the work. We will then take a reading of your trucks ECU and apply the applicable Toyota TSBs followed by flashing our tune. After the tune is flashed you will take it for a quick test drive.

Gearing and throttle response customizations are included in the tune at no extra cost.

This entire process can be completed in 30-45 minutes, depending on platform.

While we don’t work for Toyota to speak on behalf of warranty status, what we do know is that 1000’s of trucks have been tuned with OTT and we’ve yet to hear reports of warranty being denied. It’s important to highlight that our tunes are discreet and not easily detectable at the dealership level. For example, most OBDII Readers can pull CVN, however to our knowledge Toyota cannot verify CVN or has attempted to verify CVN at the dealership level.

Also, warranty claims are not common on these trucks given their world-renowned reliabilty and a warranty component would have to be proven to be directly caused by the tune. What’s more, dealerships thrive on warranty repair work and are not readily seeking ways to deny these claims. 

Clients have had warranty claims approved and completed on tuned vehicles with no issues. In fact, even our own OTT tuned 2022 Tacoma under warranty has had warranty repairs without issue. Please use your best discretion when considering tuning your vehicle. 

Absolutely. We retain stock ECU files on hand at all times and will happily return your vehicle to stock if you wish.

Our most popular trucks are the 3^rd and 2^nd gen Tacomas, 4^th and 5^th gen 4Runners, 2^nd gen Tundras, Lexus GX470 and GX460’s and FJ Cruisers.

A Pedal Controller for instance is $400+ and does throttle response only.

Our tunes are custom-developed on the dyno and in real-world driving to set throttle response to a custom setting that best matches how you use the vehicle, PLUS it also improves the vehicle’s ignition and cam timing, and completely retunes the shift logic in the automatic transmission, adds a bunch more needed horsepower/torque, usually better MPG and vastly improved drivability. For not a lot more money than a Pedal Controller, it makes a performance tune a no-brainer.

Yes, that’s one of the things that makes OTT tunes stand out above the rest is we make considerably more power vs stock – proven by dyno claims. Typical power gains for a 3^rd gen Tacoma are +23.81 ft/lbs / +18.08 HP.

OTT 9.0 – Blue

YW Blackhawk Premium – Green

KDM 10.0 – Yellow

Stock – Red

Possibly. In our case we saw an immediate 1-2mpg increase in fuel efficiency on our 2022 Tacoma TRD 6 speed manual. Every vehicle is different. Based on your axle gearing, tire size, and driving style, you may see an increase in fuel economy — many clients do.

Dyno tuned and real-world tested, no other tunes add more power, driveability while maintaining reliability than OTT tunes. Tuning with OTT dramatically improves power throughout the rev range, especially low to mid range, while sharpening shift points and improving throttle response with several throttle maps to choose from depending on your truck and preferences.

Main improvements are:

• Better throttle response
• More torque and horsepower throughout the rev range, especially low end
• Considerable power gains vs stock
• Smoother, more predictable shifting
• Reduced gear hunting
• Improved towing performance
• After a tune, it feels like you’re driving a new truck – how it should have come from the factory.

Options are also available for:

• Throttle sensitivity preferences (including ECT power throttle setting bump)
• Auto or Manual transmission
• Gear lock tune
• Tire size
• AGM battery charging
• Gearing

Our customers love them! Many have tried the rest and ended up here with a tune they’re finally happy with. Your truck will feel like it should have come from the factory, with a new fun factor you probably didn’t know it had.

Since our tunes have octane-learning you can use 87 octane or higher. If you use a higher octane, the tune will learn the new octane and increase performance accordingly.

Yes, if it’s not already updated we perform this service for free with any tune.

We strongly believe Overland Tailor Torque Tunes are by far the best tunes in the business and we use it in our own truck! We always use the latest version of the Overland Tailor Torque Tune created by Overland Tailor.

Unfortunately no, at this time an ECU tune cannot correct speedometer discrepancies created by larger tires. An aftermarket product is required.

Yes, we cover the entire province of Alberta and are willing to travel to almost any destination for a fee.

Yes! We’re so confident you’ll love this tune that you can test it for 30 days and if you don’t love the feeling of your truck vs stock we’ll happily refund 100% of your investment. However all we ask is that during those 30 days, you give us a chance to update your tune as you may prefer a different throttle setting to make sure you love it.

Unlike the “other guys”, your investment includes unlimited tune updates at no extra cost to you, not just during the 30 day guarantee period but for the life of your truck.

We accept Interac debit payments and all major credit cards via Square, as well as EMT and cash.
