I'm basically at the same step as you! Just got my green light last night and sent a log immediately after. My previous 18g tune, I just felt something was entirely off.. Too rich, too weird of boost, I don't know.. hard to describe. So far, car feels pretty smooth even though my boost is not touched yet. I hit only ~16psi max at WOT with my 18g and it felt like "stage 2" power. That's gotta be a good thing.
