He is about to start the build, so it is best to stick with the proven tune rather than hope for the best and wait for someone's "HUGE plans" to realize. And when you look at ProEFI plans, they are not even huge. Pretty standard stuff. Old fashion PI. The best part of their plan is flex fuel sensor capability, but Procede has it working already...
