Default 94 octane with Cobb stge 2 (93)?

Before the reflash I would use Sunoco 94 octane in my WRX, I now have a Cobb reflash mapped for 93 octane. Should I keep using 94 octane or just go with 93? Thanks

It will not hurt to use the 94 octane but at the same time I doubt its helping much...Save yourself a few pennies and run the 93 octane.....

Typically, unless the car is tuned to take advantage of the extra octane, nothing is really gained but a little det resistance. In the case of the Cobb products, there should be a good safety margin in there anyhow so 94 would just be redundant.
