it's all stock right now. i am not rich by any means. i am looking for some extra power and over all want to bring my truck to atleast to above par status. i realize it's a 4 banger 2.5 and that it's not going to be a race truck lol (unless i drop that 360 in it lol) but i am just looking for tips that will help it run like a champ and for a loooong time.
