My 2001 Italian Stallion money pit build

There is a little embossed square in the center of each light portion on the front of the headlight housing. On my car this is 23 inches from the ground. The cutoff for the beam pattern must not be higher than 23 inches at 25 feet.
Yes.

Little update... I attempted to "tune" today. Basically just fumbled with tuner studio, cursed alot at the serial to usb cord until everything connected with ms3basic, then freaked out some more.
The car was running pretty rich for a while, (11.5-11.8:1 wot at 7100rpm) and I just kept making small percent changes to Fuel VE Table until i got 12.9-13.0:1 wot at 7100rpm Feels stronger now, but who knows. I couldn't figure out how to find the virtual dyno software.
Then, I changed my vvt table from this...
To this...
And holy **** that made a huge difference in low end acceleration. I don't really understand how, but now the car can be on cruise control in 6th at 40mph. Accelerating requires much lower throttle inputs than before. Really staggering. I probably messed something up.

I was mostly wondering how it would affect things re:engine braking. I.e. if you step off the gas during cruise. That's a pretty low load and not really something you'd see out of vacuum, no?
I have no experience tuning VVT. I just thought that similar logic would apply to this as it does to spark advance.

So, just to clarify, I can try values of up to 40 on that vvt table? I will take out values before 1500.
Also, is there some way to get ms3 basic to hold a specific afr? It doesn't follow the afr table, but I think thats because I adjust the Fuel VE table (which i dont really know what this does, V just told me to alter this when adjusting fuel for different altitudes, so that's what I've been using)
Should I be setting the afr table to the values I want to target, and not using fuel ve table? Can I set an afr hard limits at various rpms?
Is there a graph where I can mess with the altitude fuel correction? I vaguely remember seeing a curve that could be adjusted.
Sometimes the afrs keep climbing and other times (same altitude, and settings, just a different pull) they stay rock solid.

dude you need to start reading up on ms tuning and don't touch your car until you actually know what you're doing. no offense of course, but you're seriously just pecking away and copy/pasting stuff into tables that you don't even have a shread of a clue of how they work or what they do. and that's how people blow stuff up and/or damage their engine

The problem is that lots of settings interact, so you need to learn a fair amount about the whole picture to make constructive changes.

Update!
LOVE THE MANUAL STEERING!!!!
Turns out I had over 8 degrees of caster, so that was why my steering effort was extreme.
Just got an alignment today with regular (i was running extended length) ball joints, and my caster is now 4.5.
I'm actually surprised how light the steering is without ps.
Even parking lot stuff is very manageable now.
YAY!
