I have a ‘16 white ATS-V that I bought two years ago. I am just now starting to put on mods and a tune. Working with the Tapout team has been great!! Doing the research online of who to buy parts from and who to have tune the vehicle was pretty obvious to me. Now that we have done the blue package and tune, the car feels amazing and I know I made the right decision. The customer service is what I think I like the most. To me, I think that lacks in a lot of businesses these days but not from these guys!! Parts were high quality and had instructions to make it simple. Everything was quick and efficient!! A very well oiled machine!! They make it easy to want to do the experience all over again with the next performance package. I hope I get to soon!! In my opinion anyone in the Cadillac world needs to be talking to this team to get their car dialed in!!
