I am looking to get more power so my truck is faster. I have a bunch of friends with fast diesels, and fast gas trucks too. I want to be a little bit faster than I am. I plan on putting headers, and a new exhaust on my truck, and i also want to chip it. But i cant find a OBD11 port, is it possible my truck doesn't have one?? My engine is the 5.8 liter v8.
