Isx head question

[ahm700]

Ok got truck back together. I replaced head,both fuel pumps,damper,front and rear motor mounts,cab bushings,low and high fuel pressure regulators,fan clutch,rear main seal,Bell housing gasket and clutch. Around a year ago had a shop replace clutch and rebuild transmission. They put the wrong clutch in it the springs on the clutch disc was hitting fly wheel bolts. I have been running for about a week or around 2500 miles and seem to be in the 7 mpg range. I am running the 650 tune and will be going back to the 485 tune in a few days when I get settled into the run I going to be on. So fuel mileage should go up from there. The vibration I have been chasing is probably 90% gone.
