I'd like to increase horsepower. I don't want to post this in "2.0 mod" because modification is a universal topic. What is the most hp that anyone has managed to form in an I4 cougar? Now I do not want to spend an outlandish amount of money, I won't buy nitrous or a custom turbo. I want to find out about simple upgrades. I know there are a couple of intakes and a chip, what else have members done? What numbers have they produced?
