I have a question. I bought a GTI and the guy said that it has a Unitronic stage 2 tune and I was just wondering if there was any way that I could find out about it. I have tried to see if it has a k04 on it, but I cannot see the part number. I am just trying to get info on what I have. I have stock exhaust, only swiss cheese box with k&n. I am not sure what it is boosting, I need to get a boost guage. It is an AWP engine. Thank you for your help.
