Do not expect honesty in anything as such around here.

That said, while I have run and enjoyed GIAC tunes in Audi's, I do not expect perfection right out of the box. I know there were many iterations of the B5 S4 tunes as well as the Stage 3 AWE tune. Assumptions about perfection out of the box are unfounded. But continual improvement should be expected. The delivery (of updated tunes) is the questionable part
