why won't my LTFT's go to zero anymore???

Anyone know why my Long term fuel trims won't go to zero anymore at WOT?
here's my EFI Live log, it's a missfire log so all the cylinder counts are there, but so are the LTFT's thanks.

when you hit wot - if your ltrims are positive the pcm locks that value in. if your ltrims are negative or zero - they get locked in at zero.

there is a short instance of you file that shows you being at wot (i'm looking at ftc = 15) and you ltrims are postive numbers. notice that when in ftc 15 you ltrims are always 6.3 and 8.6

that is why most people recommend that you tune you ltrims at cruise to be zero or slightly negative...
