Here's the thing.
I got this car for no reason from a friend whom I asked what car he used (guess he decided to show me rather than tell me). He had the car new (or as I call it, a Virgin Car) but had it set up to run a low end turbo. I took the turbo off and set the car up for 484PP but after the 2nd race had to pump it up to the spec above. He had the car completely stock, not even the oil change, cept he added the turbo. I tuned it like this and it holds the road like it were on racing tires.
