I would try the following: 1. Back up your mod codes or make sure they are up to date. 2. Turn off the machine and slide a business card between the battery and the clip located on the EPCU card in the front card rack. 3. Download back in your mod co

Everytime I have seen an offset like that it was dirt on the quad-align lens.....try cleaning it off with alcohol and a lint free cloth. If this does not fix it....you may have dirt inside the quad align itself. I am assuming you have checked to ma
