Something is wrong with my car. It was down on power and the dyno plot starts to get shaky after 5000rpm. Either there was knock detection, a problem w/ fuel delivery, or a problem with airflow. Also my car stalled out and threw an SES light after the dyno, the symptoms were the same as the idle air valve failure that many 08 owners have experienced.
I am going to check the air filter today to see if it's clogged. If not then I want to look at the spark plugs to see if they're OK.
