Ok fellas. Most if not all of us have some experience with some guy who says he has more horsepower than he does and we know it because we just know right. Like "its making 500 horse", and your like "not with that pee shooter exahust and 600 edelbrock bro". There's a guy in my group of friends that seems to gain hp by just looking at his car. He has gone from "around 400" to "around 500" in the last few months. He told one of us 550. Finally I couldnt take it anymore and told him to come look at my car because I wanted another 100 horse too. Sheesh. Let's here some stories about these types of things. Sharing is caring.
