I was told, when fine tuning REVO software for VW's TFSI engine, the guideline stated to keep adjusting the fuel, timing and boost until the knock retard value reads -3.0 because that's when the engine makes the most power. Maybe it is safe to do that in TFSI engine which comes with forge piston standard.
