Odd issues with Trac control

I'll get to the point after a short breakdown of my vehicle...

2014 DCSB TRD OR
3" Revtek spacer/AAL plus diff drop spacer and driveline spacer
SPC Light Racing UCAs
LT285/70R17 Toyo AT2 at 35psi
Fuel Trophy wheels with -6 offset
(I could list other things, but they would be irrelevant to my issue.)

It first happened as I dove into a sloped left turn on a country road going about 50. I could easily describe it as a brief nudging of a "rumble strip". This happened just a few days after having the tires and wheels put on, which was just a few days short of the UCAs getting installed. After I had a front end alignment done, I figured everything should be fine.
Well... I was out trail riding earlier today and everything was completely fine with my truck. That is until I took a very subtle left turn on a normal city road going about 40. At this moment, trac control kicked in harder than I could imagine it doing so at such an unusual time. A bad time at that because the turn leads into a more defined curve at which point I had almost zero control.
Thankfully, nothing happened except a Taco owner having cause for concern. If any of you have some input as to what might be causing this, feel free to drop some knowledge.
I'm hoping to consult a mechanic soon that knows a good deal of info regarding the trac control system and any related parts that may affect how the system operates.
I have yet to do any trimming in the wheel wells, so I'm fairly certain that it has something to do with a tire nudging some spot of plastic and causing the trac control to lose its ****. I don't believe I've touched the body cab mounts with my tires yet, so I'll leave those alone for now.

Sounds familiar.... iirc vsc needs to be adjusted by toyota. Sometimes lifts have that effect from what ive read. I have an 06 with no nannies and abs killswitch, so im only speaking from what ive read and not personal experience.
