Right now I have the Stage 2 93 octane tune from Cobb. It's nice but I don't really need that extra power during the winter. I'm curious to hear what other members are doing.
When I was on the stock turbo, I just switched back to stock tune and run whatever I feel like (87-93) when the gas run out. To me, 87 felt like a slug and I stopped using it after one tank.
