Well, if there is one thing that I've learned, it how well these engines can run on a fairly wide range of mixtures, especially when on the rich side. My one dyno session showed that my engine was happiest with A/F ratios in the mid 13's.
The other thing is that our systems, like most stand alones are speed density, which depends on tuning for a particular engines VE at particular rpm values. LH knows the mass of the air that the engine is injesting and the math for coming up with an injector pulse with for a particular size injector is pretty simple. My fear would be the calculated pulse with in the higher rpms, where supposably the AMM isn't part of the equation, especially if extending the rpm limit also. I haven't used APC on any engine that I wanted real performance out of in 15 years, but I would certainly be hestitant not having a fully functional APC on an engine with this chip.
