Made in Germany
Made to the highest standards in Germany.
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 certified by the Kraftfahrt-Bundesamt (German Federal Motor Transport Authority) according to ECE regulations/guidelines 2014/30/EU (EMC) of the United Nations Economic Commission for Europe. 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 Plus the best throttle controller product on the market!
30 Day Money Back Guarantee!
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 Plus is a fantastic upgrade and is superior to all other throttle modules on the market simply return it for a full refund.
Fully reversible
GOPedal Plus does not harm your vehicle.

Installation
Quick Start in 5 simple steps
Switch off the ignition, place the key away from the vehicle and wait for 10 minutes for all systems to power down.
Now disconnect the accelerator pedal.
Connect the supplied cable in between the accelerator pedal and the original connector.
Connect the GOPedal Plus to the supplied cable. Be sure to mount the GOPedal Plus and cables so that they do not interfere with the pedals. Use the adhesive strips and cable ties for this.
Confirm the handbrake is engaged and the vehicle is in park or neutral. Turn on the ignition without starting the engine.
Depress the accelerator pedal all the way down slowly and hold it for 2 seconds.

These guys are pros and know a lot. He went out of his way to explain to me different types of exhaust systems and which would work best. I will definitely be back to the exhaust system now. Thanks Madness. Oh and this throttle controller. Best purchase thus far.

OMG the gopedal by madnessautoworks is crazy! I turned it to the max and immediate acceleration, with makes the pedal very touchy! I used m old magnetic cell phone holder to stick it in the vent for its holding spot. I'll look like a lead foot everywhere.

I’ve been using the Bluetooth version for about 6 months and highly recommend it. I removed it yesterday before I took my car to get a service and the car felt so sluggish. It really is amazing the difference it makes, I drive on the max setting. Normal mode feels like dynamic mode now. It literally takes less than 2 minutes to install.

Been running the Madness pedal for several months now. At the point where if I turn it off the car feels borderline undriveable lol. Kinda wild how much of a difference it makes.

For those who are skeptical about this or are curious about the GoPedal, this is my honest opinion. It makes a difference! The pedal response is a lot quicker than factory. It takes less to feel the turbo pull. Since I’ve installed it( 2days) I’ve liked it a lot. Even on eco mode, you feel it pull better. And the installation was very easy. 10 out of 10

I just got one 2 days ago. Definitely changed the throttle characteristics. I found Sport or Sport+1 to be idea.

Eric Rudolph Gunzel
I was a skeptic, however I am pleased to say I notice two important benefits for myself. 1) I heal & toe all the time and to have immediate throttle response to get proper rpm is essential. Problem solved. 2) At freeway speeds the ability to downshift and get immediately to the power band has been a delight. Thanks

I love my GoPedal. Had it turned off by accident at the drag strip last weekend for 1 race, and got a HORRIBLE start because I was used to it being on!

Three words - HO-LEE-SHIT, every stoplight is a drag race, why not! Max the curve in sport+ mode and away you go. Installs easy, soft side-channel locks to grab retaining clip edge and two bandaids for sausage fingers to hook it up. Slid cable behind console gap at the floor with control setting at end of the seat track. Money well spent.

I got the Go Pedal for Christmas and absolutely love it. While it adds no horsepower on paper, it feels like it does. They told me when I called that it would feel like a whole different car and it does. I highly recommend it to anyone.
