I live in California and I'm thinking of buying a EVO. But I have heard rumors that the lame 91 octane gas with all the environmentally friendly additives will make the EVO put out a lot less hp. Is this true?

What exactly is the difference when it comes to the performance?

(96 RON + 86 MON)/2 = 182/2 = 91 (RON+MON)/2
So just singling out the RON number CA AZ CO are at 96 RON.
We're still waiting to here whether shiv's low wheel hp figures for the Evo ( ~180 whp ) are due to sick evo's or sick gas or the again something else

Unless I'm mistaken you're not going to see any gains in HP due to gasoline. As zx6r indicated, bad gasoline or lower octane levels that cause knocking will reduce your performance, but it doesn't seem like to me that having higher octane gasoline is going to net you any gains over factory specs. People run higher octane gasolines through performance engines to counteract the knocking caused by high engine temps and compression.
