You answered yourself. I'm never going to use it. I'm already on R888R tires in the front, drag radials and drag wheels in the back, it's not so much regret, as it's.. I didn't need to do this.
I'm also way deep on a drag build, so YMMV.
I don't wanna.. get too far off topic here, but are you suggesting you have access to the same quality of food and shopping as major metropolitian areas (NYC/LA/To a much less extent Chicago/etc)?
The valve motor not being attached should absolutely throw a code. That’s why the little plate things are sold. Perhaps it’s coded out in your tune.
