Premium octane pump gasoline plus octane booster, specifically Lucas octane booster. $8 to $12 a bottle and it can treat up to 25 gallons of fuel. It's proven to raise octane by 3 numbers so 91 AKI octane fuel becomes 94 AKI octane fuel. (94 AKI octane = 99 RON.)

Our engines come from the factory with an 11.5:1 static compression ratio and a "wideband" flat response knock sensor.
The high compression, increased detonation resistance of the fuel, plus the ECU's advanced knock detection capability causes the latter to advance ignition timing, run cleaner (via increased combustion efficiency) and make extra power.
Note the increased power and higher torque at less RPM the EEC market 1NR-FE makes on 95 RON fuel versus the JIS market 1NR-FE makes on 91 RON.
Assuming similar gains with 99 RON fuel it would be good for roughly 103 PS and 145 Nm or 101.59 horsepower and 106.95 lb-ft of torque. I've never validated it via a dyno, but in practice it feels about right.

It can potentially cause premature wear of spark plugs over time. Definitely not optimal long-term but it's an inexpensive short-term track oriented solution. This AutoGuide article is a good read about all the pros and cons of octane boosters.
High quality premium fuel by itself still offers decent gains over regular fuel for daily use. Shell V-Power for the win. 👍
