Love my gopedal and now madness released their new engine module that works with my pedal app. Had to give it a try since the pedal did wonders and it did not disappoint. My little ABARTH (Lucy) is very happy with the extra power. You can definitely feel the upgrade. Install was easy and now one app controls both my pedal module and this new piggyback. Highly recommend them both.

Thumbs up! Thank you Madness guys. I happen to be close to their Texas shop often and find myself popping in to see what's new now and then.
The last time I was there right before the Christmas holiday they showed me a new prototype piggyback ecm they were getting ready to release. Long story short I convinced them to let me be one of their "guinea pigs" and test one of their prototypes. It has now been almost 3 months and I have put about 4,000 miles with no issues.
This module is great. I loved using the GOPedal+ I got from them before and this module is a must have addition. The app has just been updated and I can switch throttle response and boost levels directly from my phone app. This is hands down the best upgrade I have done. I guess now they will package this module and the pedal module together and offer it as a power pack. I bought them separately and have been very happy with them. Thanks guys for letting me be one of your test guys. Very happy with the upgrade.

Love my MADNESS GOPedal plus and while using the app I noticed a new control feature for a boost module. Was not sure what it was so I called my rep that takes care of me at Madness and asked him about it. He explained it was their new module that was about to be released that would work on the same app as my pedal and would provide more power.
Sign me up! That's what I said and had them sell me their new module before they released it. Pretty easy install that took me about 30 minutes. App is easy to use. Then I took it for a drive. Wow! 5 stars! Nice job guys. Very happy.
