At the beginning of January I was doing some snow drifting. I blew off my intercooler pipe on the bottom of my top mount. Since then it hasn't quite been the same. I would have high end boost problems, my rpms would jump and I couldn't get the boost to stay consistent. On the way home today I noticed I wasn't producing boost until like 5000 rpms. Usually it makes it around 3. I'm thinking my blowoff valve is malfunctioning not allowing my turbo to create boost. Can anyone help me out?
