Achtuning was one of APR's first dealers to install software on a car. In the early 2000's, removing the ECU and soldering in a new 'chip' was the only way to get it done. Fast forward to today and we are one of APR's largest global dealers. Instead of chipping cars we now have the benefit of being able to flash them via the OBDII port. This results in massive power gains and less than one hour of down time for you and your car.

Tuning software, like the APR ECU Upgrade, tells the engine how to make more power. It does this by running more boost pressure, optimizing the cam shaft positions, adjusting the air/fuel ratio, advancing ignition timing, and more. APR puts cars through rigorous testing before the software ever hits the market. Doing this allows us to deliver a product that we can stand behind, and use on our own cars every day.

All APR ECU Upgrades include a 30-day money back guarantee with no questions asked. If for any reason the owners is dissatisfied with the APR ECU Upgrade, they may return back to our facility for a full refund, provided they are within the 30 day period from the time of the initial purchase.
