Current mods are:
Vsrf chargepipe
Fmic
Downpipe
Afe drop in filter
MHD stage 2+
I've swapped my maf sensor and there's no major change in anything. Next would be o2 sensor. If that doesn't fix it then I'm giving up.

What is your STFT during WOT? You need to add STFT and LTFT to get the full picture on your fuel trim health. If you're car is running smoothly and you have +-10% fuel trim, there isn't really anything to stress out about.
And what are your fuel trims at idle? I don't think cruising fuel trim is a huge deal unless you're having issues while cruising.
