Looking at you cardomain site if you're at 11.5:1 you should be ok with pump gas...I run 11.2:1 and the only thiing I noticed when I ran the race gas was that my wallet was much lighter...What size are your headers and what diameter are your duals?

edit: does it make a difference power wise if my compression is 240 in every cylinder? because i know most people are in the 100s. thanks
