Just installed the GOPedal in our Giulia and WoW!! Sport mode makes this car wake up in Dynamic. I set it up for my wife in eco and she's happy with that. I switch it to my mode.... Sport. ;-) Great product, easy to install, plug and play for sure. I will be buying the Max power pro chip next. Can't wait!!

I wanted more from my Alfa Romeo Giulia They have a great web sight and that pulled me in. I don't like doing thing over the internet so I called. Andrew answered the phone and took care of me like I was standing in front of him. The parts came in quick and every thing worked sooooo Good that I had to do more stuff.
