Hey all. I am looking at a performance chip for my 05. Any suggestions on who to buy from? I want to be able to upgrade and update on my own so the if there is one out there that is easy I'd like to know. Also I am interested in the pulley mod. Since I don't know much about it can someone suggest who to buy them from? I see that we have a few advertisers on the site but!!! Also what does it do for the car? I have an idea but I'd like to know more before I go spending my hard earned money. Might as well take advantage of the vast knowledge base out here before I make a mistake!! Thanks
