Honestly you can 1.2-1.3 all day long on premium fuel. The key would be to make sure your fuel system is keeping up and able to maintain a good AFR through the powerband. I would recommend you get a wideband O2 sensor to monitor your AFR's. 11.0-11.3 is a good target for pump gas.

When I say "keeping up" - I would search on the forum about fuel tuning the WUR so you can trim the fuel supply under load.

Getting the fuel system right is the key here.
