I had that same problem when I first got my SC and cam. Although my surge usually would come on, while going in reverse and sometimes during start-up. People on this forum call it cam surge, which is sometimes common when installing a new cam. Mine finally stop doing this so I think it was just a matter of breaking in the new cam and the computer adjusting to it. Just my 2 cents.
