Thats kinda what I was told by cordes. If I run straight 91 (what we got here in az) and mods r very similar to OPs, I would be "ok but close" when it comes to fuel. I can add flex fuel if I want but they would have to obviously retune and see where I can safely be with E. Anything more and I HAVE to do a cam. Fm
