I went to the doctor today to get a checkup, and we started talking about cars. He has a volvo 800 series... and he put a turbo and ECU upgrade in that. He also has a porsche with a s/c in it. He was talking to me how his buddy who has a GP put something called "aquamist" in his car, and they go to "autocross" What are these two things and what do you know about them?
