Default Just finished my first tune! What are your honest thoughts?

Hi everyone! I finally decided to learn as much as I could about tuning a Gen 3 platform. I mainly followed Goat Rope Garage's videos and referenced other videos out there on YouTube. This is an SD tune that I did.

So, without further due, here is my information.

2005 Nissan 350z
SBE LQ9
243 Heads
BTR Stage 3 LS1/LS2 Cam - 231/244 .630"/.615" 112.5+2.5
Titanium .660 Dual Springs
1 3/4 LTH
2.5in Straight Exhaust
T56 6MT

My original tune was done by a professional, but I quickly realized I did not like the tune? Nothing was wrong with it, but it had an annoying burble tune on decel, I couldn't stand it any longer. I decided to learn and do things myself as I do plan on going with a nice set of heads and a fast lsxhr sooner or later.

I really do appreciate anyone or whoever takes the time to look over my tuning, any feedback will be taken seriously. I personally think it's done?

Attached files below will be my old tune, my new tune up, logs, and channels list.

Also, another question,

When I had turned on the LTFT and STFT again, I noticed my VE AFR Err is a little less dialed in? The "Cruise Log - LTFT STFT DFCO DISABLED" log was dialed in, but afterwards, you can see it can probably use some tuning again?

Can I adjust my VE with the LTFT and STFT turned on? or am I supposed to disable them every time I make changes to the VE?

From what I gathered, I'm supposed to aim for +- 1-2% on my VE AFR Err map, which I did. But after turning them on, there's some areas that are around -+2.5%
