The thread has drifted a bit. My initial post was in response to someone who indicated they were running very lean (16.x) in normal operation (at least that was my interpretation of what they said). I didn't want new owners to read that and think it ok to run that lean all the time.
I know some of the EFI units with reliable knock sensors and the smarts to do so can go into lean cruise with appropriate spark advance and get to those levels under ideal low load conditions, conditions we on the west coast don't see as often. So, from my experience, a lot of the discussion about various EFI and carb tuning topics over the years is very much colored by where and how one drives. All the options appear to work for someone, but no one solution seems optimum for everyone.
I remain a staunch advocate for all the drivability gains one can experience from EFI, but when asked, recommend the simpler modern self learning systems for our new GMC owners. Older hands, those with lots of ancient big iron engine experience, and those interested in squeezing out all the fuel economy to be had in our coaches will likely prefer the greater hands on control offered by systems like the Howell with EBL alternatives.
