I am looking at attempting to get a slightly better gas mileage, with the benefit also slightly increase horsepower on my GMC Sonoma. I have read around and a good way of doing this is a free flow exhaust system, cold air intake, and a computer chip. I have searched around for some parts but I would greatly appreciate another persons advice who may have more experience in the area. Also I live in California and I know there are difference emission standards. If you would kindly suggest even one of the three parts I would be very grateful. Car Info...
