We will verify your truck's software version and update it for free if required.

The tunes do not modify the OEM ID, which means it will always report back as "stock"

No our tune does not, however there are other aftermarket options available. 

Although we do not guarantee warranty status, many of our customers have had no issues having warranty items taken care of without issues after tuning.

The KDMAX Pro tunes (and the VFTuner platform they are build from) are tested on our own vehicles! This can mean months of testing before we even get updates to utilize for our custom calibrations. 

No, the KDMAX tune is written to the vehicle and will remain in place until the ECU is replaced and/or the calibration is overwritten.

If any prior customer every takes their vehicle into the dealer and has their ECU updated for some factory update we will need to reflash the custom tune to re-apply. This is at no cost to you, we just need to coordinate the visit. 

The tuning platform we use (VFTuner) indicates that any tunes produce can at no time be used on any emissions control vehicle that is used for anything other than off-road performance or competition use. ALL Ecu tunes, Calibrations, flashes, files, datalogs, or anything in regard to the tune, tuning process, changes, are for OFF-ROAD USE. 

OUR TUNES AND FILES CANNOT BE USED IN ANY WAY TO CIRCUMVENT EMISSIONS REQUIREMENTS WHERE YOU LIVE FOR ANY REASON. THIS REGARDS ALL ENGINES, ALL ECUS, ALL FILES REGARDLESS OF CAR, MAKE, MODEL ETC. THE SERVICE CHARGE FOR TUNING IS SPECIFICALLY FOR YOUR ECU FOR TRACK AND OFF ROAD CONDITIONS ONLY. 

- Any files or calibrations are developed only for the exact vehicle and drivetrain that it comes with from the factory.

- Calibrations do not modify or disable any emissions check, component, monitor

- calibrations cannot be modified to disable any reporting component

- calibrations cannot be modified or used for any vehicle except for the intended vehicle, exact ECM, and specifications that came from factory.

No, and for that reason at this time the calibrations cannot alter the shift points and throttle settings while Adaptive (Radar) Cruise Control is enabled. While engaged, your vehicle will still function with factory settings (untuned)

Of you hold the cruise control button down for 3-5 seconds you will enter the Regular (Constant Speed) Cruise Control  mode. This mode has our updated KDMAX Pro settings.

We have word that an update to our tuning platform (VFTuner) is coming that will allow some level of access to improve the adaptive cruise shift/throttle mappings. Release data is TBD.

• Please send "TWTaco" a message on TacomaWorld.com
• It is expected that you would purchase your own tuning "Pro" software license and cable (VFTuner.com). This requires that you have an established business.
• You would also need to have your own laptop and technical ability to install, setup, and troubleshoot communication issues should they arise.
• The liability is on you so proper understanding and also business insurance are highly recommended. Most vehicles we tune are $40k+
