How lean is too lean?
From a cold start my car runs fine...relatively. Usually AFR #'s around 14.8 to 15.5. However once it has warmed up It runs around high 16's to 18.
I understand this is pretty vauge and could produce more info when needed..(to the best of my newbie knowledge) I have already done a boost leak test and came up with only a small leak on the BOV gasket. Held all the way up to 20psi...
As far as upgrades I use a lazy-Z pipe to carry the air to the turbo. The turbo is a standard 16g, Standard throttle body. Port-matching and cleanup of intake manifold runners, Ported head with HKS 264 Intake cam HKS 272 exhaust cam, Standard valves and pistons. Also has adjustable fuel-pressure regulator and fuel pressure gauge, and wide-band O2 sensor.
No form of engine management...
