If it continues to knock with the new fuel, load a lower octane tune. It's not too uncommon for fuel in certain areas to be a bit "off" of their rated octane. It's posible you may just need to pull a degree or 2 of timing with the tuner. Altitude can play a role as well as other things. % ethanol doesn't always help, either.
