95 suburban 2500 6bt

19mpg on the highway w/ a suburban is pretty good, no?



what's your timing set at? if it's low, that could account for 1-2mpg

Yea 19 is ok for the highway but I am looking for 21-22 on the highway and 16-17 in town. My timing is set to stock. I was told to set it to 17 deg and run a 3000 govern spring.
