Hey guys, I own a BA mk ii xr6 turbo and am having boost issues. A couple of weeks ago my car would only hit 9psi in all gears (on a 15psi tune), then it went down to 6psi. I did a boost leak test and found a leak and fixed it. After I fixed it, it would hit 12psi. It was fine for a day and then same problem, found another leak and fixed it and would hit 12psi again. Then the same problem again, would hit 6psi for about a week and a couple of times would go to 10psi. Have done another leak test and found no leaks. Just wondering what you guys think it could be? It has a 12psi actuator, could this be faulty? If so how do you test them. Also must add its never hit 15psi since I had it, in any gear and have owned it for nearly a year. Cheers guys.
