@yorkirs, not to highjack the thread…….. California, Arizona and Nevada has the lowest octane allowed here in the states. The if you use a Cobb Access port there is a specific AZN tune for us suckers.
Others states in the US has 93-94 or in rare occations 97oct on from the pump.
You can buy 101 octane gas in metal gallons…… it was worth it when I had my Evo IX and X since during that time 91oct gas here is as expensive on the metal containers.
