Would the KB be a waste if 91 octane is all I want to run, or do you guys know of an advantage the KB gives over the stock besides being able to boost more? In other words, if I run 14psi w/ the eaton, what advantage is 14psi w/ the kenne bell. It seems that I'll already be pushing the limits of 91 octane on the eaton? Would anyone like to convince me to change???
