So, today we got that tamper proof bolt out. It is amazing what an impact driver will do...

#11 plate, slide approx 1 mm forward of stock position. It really cleaned things up, as far as power band. It seems much smoother now. Very much snappier as well. I made no adjustments to the AFC, other than sliding the housing forward.

The truck did smoke stock, and that is all cleaned up now. All that remains to be seen is what happens when I tow a load behind it...
