i typically get about 14 all in-town & about 16-17 if it's 75% highway @ 60-65mph. that's with 33s on 16s, 3.73s, LTs, ORY, airaid intake. that's on a mid-grade tune (maybe .5mpg less than the 91 tune i had before). also consider i'm at 3500-4000' & we regularly have crazy wind (30kt+). in TX running 93, i'd see around 18mpg hwy @ 75. in FL with my 31s, i'd seen as high as 20.
if anything, i'd get the A:F doped out first before making any other decisions... not that a cam wouldn't help anyway
my tach reads right - it didn't the very first time, but that was because i did the math & figured out Jesse programmed 4.10s instead.
no cruise in my truck.
maybe some other guys could chime in with their results
