Also just looked again.. Dropping into and out of closed loop.
You can uncheck any of the traces on the log.
Try to deactivate some and look at only rpm, the closed loop, afr commanded and actual.
I'm wondering if the alky system is being sucked dry and messing with the afr.
Is it using a lot of alky?
Maybe turn the boost down, kill the alky, and see if AFR commanded and actual are close.

You might want to take a look at your fuel table, it is pulling 30% fuel in 1st and 2nd gear. At about 2.2 seconds in the fuel flow jumps around 176lbs/hr when it goes open loop.
thanks Chuck for your time and help.These 6 passes were the first WFO pulls and you are correct it is rich. Now I have 1 saved log I can try to find the other 5 in the computer to compare.
I have closed loop correction on because my WFO fuel table was not a very educated guess
But in the lower RPM rang that part of the fuel table is very close.
Im logging ALKY PSI and it appears to be tracking good with the boost.
the timing table and AFR table is a copy of my 6.1 TT chip took hours to extract that data. ALKY pump is new and tested good. ALKY is back to the default settings as a starting point. Now I try to decide to remove ALKY,Fuel or add timing.
Thanks you too TType yes the table is just a guess using Holley setup info so I need to work on the higher boost and RPM portion of the table after I hit post I'll post the tune.
Like I said the timing and AFR is off the TT chip Its not in stone so Im going to revisit AFR at ALKY turn on, like I said above there is options to fix the rich spots
Im not convinced that 3 or 4 Dyno pules will tell me much more than what I have today
