Target AFR & Actual AFR WAY OFF!! HELP

So i finally got my car to stop leaning out and i figured id start logging afr to clean it up. starting rich obviously. well theyre all off 1.0+ and the difference changes between load. so i decided to re clean up my maf scaling.(which made me start hitting 290 load at 24 psi) so i did so through tuner helper. only did cruising and idle. no wot pulls. but i just can get the afrs any closer together. or even predictable at all. theyre all over the place. im wondering if anyone has any input at all or can guide me. im newer to this to im trying to get the hang of things because i truly enjoy this part of automobiles.

starting to feel discouraged and wondering if i should start looking for a good etuner.

log of last pull. (hit fuel cut)

Start here, get a basic understanding of what the ECU is doing and why.

Also, Load based or PSI based?

As I've told you already. Fueling numbers in the fuel map will never be a 1:1 reflection of your actual AFR.

The moment you stop thinking they should be will be the moment all your frustration will fall away.

It's not a target AFR table.
