Yes , If that is what your asking then yes , If you could controle Cyl temp in another way other then adding more fuel then you could run it leaner
The MS3 guys are learning the hard way that 12.6 isnt the safe AF as I told them that a few years ago , I build a few engines for the MS guys as well and play in them some
Just because you inject the fuel directly into the Cyl under high psi does not change the AF ratio needed to keep it safe , Direct Cyl injection is more for emmissions and MPG more then anything
