Okay. Well, for performance wise.. I have the resonator delete, 3" cat-back exhaust, and a filter in place of the stock air box, and I was just wondering why sometimes I get over 7 second 0-60 times? Isn't the stock average like 7 seconds? Is it because I don't do the run while my car is cooler? or because my wheels spin a bit at launch? I feel like this is such an amateur question, but I trust you guys over the rest of the internet. Thanks!
