I dont know how to further reduce IAT's since i have a supercooler and separator valves...?
I would drive the tank (nearly) empty, and then use a quarter or half tank of higher octane for testing. Here in Germany we can get 98 Octane on every gas station and 100 octane on selected ones.
According to IATs : for example more Volume of IC-Fluid in the separated System, IC-Heatwrap, more flow with stronger Pump etc.
