I have been reading about cam surge. What I have read has mostly been on efi GM products. It is explained as a slight surge while driving under 2000k that is not present at highway speeds or any other time. A lean condition from running a bigger cam mild to med. ON some of there forums they say a tune can minimalize it. I have just been googleing it. Don't own a GM product. Just wondering if any one here has had that problem and determined it to be cam surge? I am having that problem on my 5.0 right now. And yes I checked the surging idle check list, pulled codes (11), checked for vacuum leaks. Iwould love to hear ideas but I mostly want to know about cam surge. Is something that really requires tuning out or just a name for "I can't fix my surge so I'll call it cam surge".
One other thing I was wondering is would having a f303 cam and a gear ratio like 3.08 cause a surge issue? I know it might get in the right rpm quicker with a better gear but would or could it make it surge below 2000K?
