Good afternoon everyone, I just purchased an '07 GTI/ Rabbit over the weekend. It has cold air intake already in place. I'm currently working on doing the timing belt/water pump since I was unable to verify that it had been done by previous owners and its sitting at 143k miles right now. After doing this along with spark plugs and a valve cover gasket I had planned on looking into tuning the vehicle. I'm just curious if there is a way to find out if it had already been tuned or not. Is there a way to find this out?
