We will offer our standard tune updates for no additional charge. Which means that if you're running our map "1.02" and we, for example, fine tune an additional setting that makes the car shift smoother, or faster, and have an updated "1.03".. you can download this map, flash it to your car, for no additional charge. Will hold up to 5 tunes + stock, plug in, flash your tune and go.

Our tablets will also come with a program you can install on your PC that will allow you to manage it for updates. We will have updated tune files that can be downloaded directly and loaded on your handheld.

For example if you're running our "91 octane N/A Bolt On Reflash 1.02" and we have an updated version of this tune in the future, you can download the 1.03 tune patch, load it onto the tablet, upload the newer tune and go. Which means you will always have access to our latest developments, and future tunes.
