Yes sir it's been partially disabled for a while but now it's 100% inactive and only the IAT sensor part of it is working which is necessary for the MAP to control fueling in a speed density setting. Not a real major reason to do this other than my eventual goal of deleting it completely in preparation for boost. Also learning to SD tune this will help me for when I finally get my RCSB back together.
But the drama isn't over yet lol. Still super-rich not sure it's taking the changes as well as I'd like but I'm only correcting by half% I just figured it would have been more of a drastic change after 2 changes.
Here is the latest run, it did do a weird crazy rich spike in the beginning like 9.0afr for a good solid 30 seconds but cleared up and went back to being just a point or 2 rich which averaged the data out to this.
Also got a little lean on the top end, I need to bring the limiter back below 6,600 I know these heads don't flow that well.
Lastly, heres a couple snips of the O2s at different spots in the tune, they both start out close to even with each other and then suddenly jump drasticly apart with the B1S1 making the more drastic swings. Not sure if one making larger swings than the other means anything specific.

Also got the steering stabilizer in and on, it's pretty easy despite a complete lack of instructions and multiple unused parts. I don't have a ton of faith in this shock lasting a long time but as a quality affordable replacement I'll probably try to find a rancho 9000 adjustable like @kbuskill just put on his truck. Which is why I posted pics of the shock length for my future use, also some pics of full driver, passenger, and center clearance.
Overall impressions on my 3 mile test loop is that it does effectively dampen the bump steer that will always exist in some amount. Anxious to see how it does on the heavily pitched and totally fubar farm roads during my commute tomorrow. Maybe I will be able to hold the wheel with my knee while shifting, drinking coffee, and passing semi-trucks.

That looks like the one I put on my 02 a couple years ago. Last time I pulled it off ( couple months ago) it seemed to be working good.

That's good to know, some of the reviews said after a few months it began to leak shock oil but, if it ain't broke I will not fix it. I'm sure blown awd launches put a little more stress on yours too
Tuning is making great progress except I did get a tad bit of knock this morning @22*. I pulled what it detected out of it till I get fueling 100%.

I just gotta put in the time! I was half-assed tempted to cancel my rental and take the Tahoe on my trip to Florida this past weekend. That would've given me lots of log and learn time. But it was a rush trip and I had too much else goin on.
I'll start a convo on this in my build thread to not clutter up Dan's thread. But, one question: Is there a "safe" forum or thread on HPT's site where an absolute noob such as myself should get my feet wet? I don't wanna jump in and try boxing with the champs when I don't even know the ring.
