Truck is getting around 10 mpg on average. when it was newer it would get 14.
The engine was completely rebuilt (by me done right) the only aftermarket part is replacement injectors from 5.0 motorsports, who i called and they assure me the injectors are drop in replacement for the leaky stock injectors.
But the truck was getting bad mileage before the rebuild. has almost 400,000 miles on it. Oh fresh transmission also.
Im attaching my log and config, i think the maf is bad but im not sure.
