97 7.3 poor fuel mileage
 

Hey fellas new to the site wanted to get yalls tips on something I got a 97 f350 7.3 I've got afe intake driven diesel lift pump built trans suncoast kit ts tunes with swamps tuning and here lately it hasn't been doing good at all on fuel mayb 150 160 if I'm lucky and yea I know it's a diesel it won't get great mpg but it's killing me in fuel and when it gets warmed up it idle surged sometimes. I've already unplugged ebpv, just done service about 2000 ago and it still sucks on fuel yalls input would be nice thanks!!
