Saw a 7.3 go from 18 mpg to 11 in under 6 months

Buddy of mine in Phoenix ignored a small coolant leak for way too long and it cooked his injector cups. After replacing them and a set of injectors he's getting worse fuel economy than before the swap. Anyone else run into this where a fix makes things worse instead of better?

Did you try recalibrating the injectors with a scan tool after the swap? Sounds like his truck is just dumping fuel now instead of burning it clean. At this rate he'll be saving money by walking.

Man walked right past free gas money? Unreal.
