So why did commanded lambda shift to 1.0? Well it seems that the ecm will do whatever it takes to control torque. The added 2 psi and ignition timing caused the engine to exceed a few of the torque values in the tune. Appearantly Ford thought it was a great idea to cut fuel as well as a few other things to limit the engines torque. Needless to say, not a good thing for a turbocharged/supercharged 5.0........

This is definitely a common thing with the new 2011 models. Ran into this exact issue tuning a 2011 F-150 we supercharged here couple of weeks ago. You definitely got to watch those things. They'll bite you quick.
