94 max distributor adjustment???

this is my first efi mighty max and i'm wanting to manually override my computer's automated timing curve by 2 or 3 degrees, anyone know if there is a bolt to loosen to manually adjust the distributor???

Yes there is a bolt I believe its on the top portion of the dist. and you can turn it to change your timing. I dont have my truck anymore so I cant go take a pic, but you can do this.
