I dont believe I have an answer or solution. I would like to add more thoughts.....Ford is happy with .68 but the engine is highly detuned per say....and super rich....LMS steps in and develops tunes delivering more power and their at .74 but also very rich...and one if not the first to tune an Ecoboost ...perhaps .74 is a step in the right direction while playing it safe as much was still unknown or not tested enough at that point....then you have other tuners stepping in after the fact coming in at .80-.82 and theres more than one tuner or company using that lambda ....is that because it's been determined to be still safe? Is it still not (very) lean? We went from .68 (very rich) .74 (less rich) so now is .82 very lean or is it just right? And is .82 adequate across the board for whatever mods you have in mind (upgraded turbos, internals? So is the slight increase in power from .74 to .82 more or less in line with the extent of your modifications currently?
