i'm gonna say it again: MBT means maximizing torque. more torque means more fuel. this is for power tuning.
in cruise you want to tune your AFR first and use timing to keep the burn in the cylinder. so what if you're beyond MBT in cruise? you've already changed the game by reducing fuel.
just raise all your timing into the low 40s
and raise your AFR targets below 70kPa to 15.5:1
stay off the gas on the highway.
you wont destroy your car.

Anyway it does seem this whole thing is pointless.
Trey, you can't get better than 22mpg with an 8:1 compression motor.
