VP MS103 vs. Sunoco 100 (CAM2)

Place that was on my way to work that carried VP fuels closed down. Now I have to drive out of my way to pick 5 gal drums of MS103. No big deal but I know there's a local Speedway station that carries CAM2 at the pump and I think it's cheaper then VP. I was wondering if there's any one here that used both and could tell me: 1) Will I need to retune fuel and timing significantly 2) Is CAM2 easier to get knock?

I have a stand alone with out knock control. I would hate to try CAM2 only to start knocking on my current tune. Please, I need to know from people who tried both in their car not from "my buddy put cam2 and his car was faster".

CAM 2 is leaded i believe which helps reduce knock. Try it log it see how it goes i wouldn't spike the boost up too high right away.

WTF You might want to check Sunoco website first before you type. It's unleaded. Sunoco leaded fuels start off at 110 octane.
