this is a great write up for people to learn how the fueling on these trucks works. but i have to admit, i would have gone about it another direction. i would go to 181's for dvs and i would have left the 100 and tuned the afc to control the fueling levels. i would bump the boost up a bit more, i had one of mine at 42 lbs for over 60k and it was not terrible with the 370s as far as smoke goes. the afc is a really great thing when setting the fueling curve on these trucks. jim fulmer shower me a set up he used years ago, nothing more than a regulator that you hook up and use it to set the fueling curve of the afc. and you will learn all kinds of things with it. like that a 215 pump afc spring will not compress all the way till 40 pounds of boost. still this is a great write up and i will send many people this way to get some learning.
