The drop in torque from that same leaning one hour of the HSN
It's mostly believed that the leaner you go the more power you get. Blue line was leaning the HSN just 1 hour after the pull of the black line. A significant drop in power without stalling or cutting out, only the dyno caught it.
More torque was requested. A little off the top end but nearly doubled the torque.
O.S. Max 12TG V5. +0.6 hp and 4mph

Temperature is good for reference, but you can have lower temps and lean conditions
