Unlike most of our competitors we do not produce our hardware overseas in factories that do not have to adhere to strict manufacturing processes. Most of our competitors chose to source their hardware from China or Turkey to save on costs. We believe your safety is of the utmost importance. Because of this we manufacture our hardware in Germany to the highest standards. It may cost us more to source hardware components from Germany, but we do not think you should put a price on your safety and the safety of your passengers.
Our hardware has been approved and/ or certified in accordance with 2014/30/EU (electromagnetic compatibility) for your safety. In addition the hardware is manufactured to the strict guidelines of VDAT and TUV.
At this time USA does not mandate that throttle modules get safety certification (like the EU) in order for them to be sold. Even though it is not mandatory in the USA, we feel your safety is important. This is one of the many reasons we source our hardware from Germany.
The best hardware along with the newest and most advanced software makes the GOPedal the best throttle controller product on the market!
Be sure to also check out the new GOPedal Plus that offers additional features.
Intelligent calibration automatically detects and adjusts accelerator pedal signal for seamless operation as needed.
Our MADNESS GOPedal features a wired controller for ease of use. You can also add on the Bluetooth Option in case you would like to use your smart phone instead of a hard wired remote control. Our wired controller and/ or the optional Bluetooth Add On and App feature makes usage and control a breeze!
Don't take our word for it. Use it for up to 30 days and compare it against the competition. If you do not think the GOPedal is a fantastic upgrade and is superior to all other throttle modules on the market simply return it for a full refund.

No, the MADNESS GOPedal does not have any impact on the engine performance or lifespan of your vehicle. The driving style and the level of care taken are much more important factors in the operational reliability of your vehicle.
