I have taken my car many times to the dealership over the course of a couple years. after another dealer messed an oil change up, and I made three dyno pulls with no oil (and no the idiot light did not come on). I have always been suspect that that hurt the motor. Even though the dealer has said every time that there is nothing wrong and that they notice no power loss. I was starting to believe that this was all in my head until late this summer. When I was beat by a m3 with 220 horse to the wheels. and by an lt1 camaro. Both cars that I should be able to beat.

I have noticed that after one pass she only spikes 10 psi and then falls to anywhere from 5-2 psi. Also in the past the car would run at normal temps. when really getting on it. Now as the turbo kicks in the temp shoots up. The car has no pull anymore, the motor seems tired.

I know this is vague and I wish I could give more detail but I am not hip to cars with computers. And this is the first car with a turbo that I have owned so still learning with that. ( i am the original owner, guess I am a slow learner) So since I am tired of my dealership getting free rides. Any ideas on what to do? or what it could be? I am thinking about getting it dyno tuned but do not want to spend the money if it will not fix anything.
