I'll just say this.. if you are actually trying different fuels, and not making tune-up changes according to what your combination wants for that particular fuel, you just may be missing the advantages to that fuel.. and it is easier to do it on the dyno, if you in fact dyno.. many do not, because they run the same combinations freshen up after freshen up.. so they would have to try it at the track... and believe me, O2 sensors make the difference.. it's not that easy to read spark plugs anymore with some of these fuels..

There are some fuels that are almost a direct change over, but even with those, a little tuning would make things better..
