Frequently asked questions regarding the MADNESS GOPedal:​

Would I not get the same effect simply by quickly pushing the throttle pedal all the way to the floor?

Unfortunately not. 

The speed of the human foot can never match that of the vehicles's electronics, and by repeatedly hammering the accelerator all the way to the floor can actually cause damage to the throttle cluster and drivetrain.


What is the difference between the MADNESS GOPedal and the MAXPower Engine Control Module?

The MAXPower ECM increases the vehicle's horsepower and torque, whereas the MADNESS GOPedal modifies the vehicle's throttle response.


Does the MADNESS GOPedal have an impact on the lifespan of the vehicle’s engine?

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.


Does the MADNESS GOPedal increase the engine's emission levels?

The MADNESS GOPedal does not alter any air and fuel ratios (AFRs) of the engine which means that neither the emission levels nor the exhaust gas filter will be affected by installing the MADNESS GOPedal.


Does the MADNESS GOPedal increase fuel consumption?

The amount of fuel which is injected into the engine is not altered by the improvement in throttle response. Driving behavior after the installation of the MADNESS GOPedal is the main factor which affects the improvement in fuel consumption.


Does MADNESS Autoworks offer a warranty for the MADNESS GOPedal?

The MADNESS GOPedal also carries a 2 year warranty against malfunction! In the unlikely event of fault, simply reach out to us and if a fault is found with the GOPedal a replacement will be sent to you.

Can I return the MADNESS GOPedal if I’m not happy with it?

MADNESS Autoworks is located in Signal Hill, CA (an enclave surrounded by the City of Long Beach) and is a facility dedicated to making your favorite ride truly yours by offering a wide line of aftermarket accessories, installation and customizing services.

MADNESS Autoworks was originally known as SMART MADNESS a company that became famous for customizing and accessorizing smart cars.

SMART MADNESS has become the largest provider of smart car parts, accessories and customizing services in North America and now one of the largest globally in just a couple of short years.

We accomplished this goal by providing the very best in products and services at reasonable prices with a personal touch. We treat our customers like family members and do our best to make sure every one of our customers gets the very best treatment possible.

A number of our customers own other cars besides the smart car and continuously ask us if we would also work and or customize their other car due to their positive experience with us. This is how MADNESS Autoworks was born.

Our goal is simple! Provide you, the driver with the widest range of products, servicing and customizing options with friendly service at a very competitive price.

After spending years working on cars and working with many suppliers we thought at times we could do better by designing and manufacturing some products ourselves. We started partnering up with our most trusted manufacturing partners and suppliers, investing in infrastructure, manufacturing equipment and recruiting some of the best talent that could help us design and build superior products and make them available to our fellow drivers.

Our goal is to provide a top quality product that has been tested and used in our own cars and has proven to last and provide a good value for the investment. Whether you are looking for the best value in a set of floor mats, a performance exhaust system, an intake, a roll cage or a carbon fiber part the MADNESS Item is designed to deliver on our promise of bringing a good quality item at a reasonable price. We do not design and build our products to be the cheapest, we design then to be the best value for the money and stand behind them the same way we stand behind our work.
