Re: a ? about my 95 stang plz help asap!!!!
Usually one of the first mods to do on a 5.0. You can go between 12-14 degrees on the timing, it depends on the octane you want to run in your car. I always kept mine @ 14 degrees. There is a computer module located where the factory airbox mounts. It's a little gray plug that has to be removed in order for the car to except the timing advance. Do you have an o/r mid pipe? If not it will help out alot also.
