I just got my TT back from the shop after doing a JDM swap, the car was sitting for 2 years prior to me buying it. It started out fine when I got it back and then I came out of the tag office and it wouldn't start, it acts like it wanted to start but just didn't. and then after sitting for 30 mins or so it started back up. any ideas? and also when I was driving it, it was only hitting 7psi of boost and didn't seem near as fast as it should be??? I just need to know where to start....
