I was wondering if there is any danger in boosting with more people in the car? Not a car full of five people, but most likely three including the driver.

I would assume that if it was tuned with a certain load on it adding more weight might throw the tune off, but I was just wondering about real world experiences..

 

no, it doesn't make a difference. It just makes you slower. I ran with 4 people stuffed inside my civic back when i was a kid all the time. I was stupid
