Wtf? Do you know what the distributor does for your motor? It controls your timing man, it tells the ecu when to send spark to your plugs, fuck with that and expect throw a check engine light, and expect your car to run like shit. You aint gonna gain nothin worth fuckin with. But there's always the exception if your runnin a nitrous kit or something, but that's not gonna give you power, retarding for that will jus help keep your motor from detonating. My advice don't fuck with it. Go buy yourself a shiny intake, it'll be a more better hp gain and it will make the sound that will make you think your goin faster. LOL
