in order to push the black smoke that you are looking for youll need injectors, and a chip. i have a 97 also it has 100 injectors, 140 horse ts 6 position chip 3 inch down pipe, and a after market turbo and i can roll coal all day long. another thing you can do is unplug your wastegate and it will make it smoke
