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.

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