Need Help With timing Issues (Logs Provided)

N55DCT135i · 02-05-2019, 11:52 PM

I have been chasing these timing pulls for a while on my car
2012 BMW 135i DCT
FBO (CP,DP,exhaust, E30 custom tune Stock Turbo)
Plugs and coils are 2k miles old and using NGK 95770 0.22. I am noticing cylinder 4 pull timing consistently. Thanks I would appreciate some advice

Lean Knock would be my guess. Add 5% fuel and try again.
