My only concern is the timing drops showing up in Tim's logs. I also am not sure why he is seeing 22 lbs of boost when the map he is running should only target 18?

14.5 afr is pretty darn lean for FI or is that OK on these motors? I've been away from this stuff for at least 10 years maybe things have really changed. The tunes we used and tweaked never went over 12.8 at the absolute most. afrs in the 14.5 range on a forced induction motor on the street were unheard of.
