I bought this car and it is my first dive into the world of turbo chargers. The car sets with over 180,000 miles and I'm getting an overboost code. When I bought the car it popped up on me and I cleared it and it took over 400 miles before it came back. I'm have done some looking into this charging system but am still very new to this stuff. I'm worried that the car might have an aftermarket turbo or some new fuel maps because when I stepped on the gas it will boost up to about 18 psi and it did this constantly for weeks without throwing a code. From what I can tell the car should be running at 12 psi max and should trip engine lights if it ever gets up to 14 psi or higher. From what I can tell I tell I need to pull the turbo off and clean out the turbo fins (I'm about to do the vacuum testing on this to check if it is really froze up) but I don't want to dive into this without asking you people because I'm not 100% sure yet. Does anyone have any suggestions?
Here is my Auto-Scan. I believe the miss-fires are a symptom of the issue and not a cause:
