mak 0 Posted July 17, 2006 If your running a standard engine adding a fifth injector will do far from improve things, more completely screw the fueling up and cause bad running. The only time you should need to use a fifth injector is if your putting more air into the engine (charging) creating the need for more fuel. And even then there are better ways to do it then using a fifth injector. Share this post Link to post Share on other sites
