DEKRA and TÜV certified
Each Panther tuning box has been certified by both the DEKRA and the TÜV organisations, whilst meeting the CE and ISO9001 safety regulations. The Panther tuning boxes have been rigorously tested in the development stage and have been trialled on all makes and models of vehicles listed on this website. An AWD dynomameter is used to trial the boxes power production and exhaust emissions to ensure that emissions remain within the permitted values and that the increase in power and torque is seamlessly provided to the vehicle via the throttle response.

Vehicle warranty
Vehicle manufacturer warranties should not be affected by fitting this plug-in tuning box to your vehicle. The tuning box is undetectable through the self-diagnostics port in the vehicle and can be quickly removed if required, leaving no trace that it was ever installed. Each Panther tuning box has undergone a great deal of development and testing to ensure its suitability for each vehicle listed on this website.

Durability and long term use
The Panther tuning box is made from top grade components which are housed in a heat-resistant aluminum composite shell. The pre-programmed increase in power and torque will not exceed the performance limits of your vehicle and all safe-guards set within the engine control unit (ECU) are retained. The tuning box has been specifically developed for everyday driving and long term use.
