Oh im just asking questions (learning) lolchimchim said:I'd say 13.0:1 for N/A and about 11.5:1 for power adder. Just a guess. If you ARE running lean, you could add bigger injectors or a fuel pressure regulator, but those are physical things and guesses at best. A custom tune is the best and safest way to do it.
EDIT: I had my car dyno'd with an A/F before my tune and it was about 13.5:1 at 2000 RPMs and steadily dropped to 11.3:1 at 6000 RPMs. It feels like my tune fixed this, but I will comfirm it on the dyno soon. Why are you asking these questions. Most cars are a little rich from the factory just to be safe. Usually anything you do on the intake side with make your car lean and anything you do on the exhaust side will make it rich. It looks like you have a good mix of mods. You're probably OK with the stock tune.
