You need a good base tune to start
fuel trims is off & knock retard around +4 degree, stop do any pull. what are the full setup
email me if you need good base map
post dyno log + tune if you need support
use the search tools
Have you figured it out
better to start with fresh good base map. lmk if you need help.
easy setup...i can help you with good base map
you should not touch the Maf table when using stock maf diameter. If the fuel trims all over the place with stock maf value then you should start checking for vacuum leaks and fuel pumps pressure.
i saw na tunes better than this. it is better to search and ask about the good tuning guy or company before losing your money here and there
what OS you are tuning, stock or whipple cal
Fuel trims 30% off, post the tune if you asking for help
start by adding 30-40% to maf curve and fine tune from there
inspect the o2 sensors extension if you have them, they could be the issue

on gen3 coyote you need a custom tune when you swap to boss manifold. shutting off the imrc codes not a good idea
maybe hitting engine or transmission limiter
First get ride off this injectors and buy something else like ID, FIC then recalibrate and smooth MAF curve.
3.5" and 1600+ whp zero issue
Better to post the tune + stock read
you need to add intake temp 2 pid and make sure you are running colder spark plugs with proper gap.
Better to swap the pcm with manual trans pcm
SCT will save what in the os as stock file and you can back to it by selecting Return to stock.
How much low boost and what spark plugs and gap
push up clip torque max indicate when tuning sc
