I'm running 13.5-13.8 untuned right now, and it's running better than I thought, but still not as good as it could be.

wow thats really lean for untuned....not a bad thing necessarily but not common at all! Reldas, you're right where the factory ecu should be. Its set to run richer in the top end to prevent detonation. The reason we run so rich is because they made the car to be able to run without premium.....even though it says it requires it, the tune doesnt. Firehawk MUST run premium or he will get detonation guaranteed.
