Well, after a major hick-up on the break-in trip. She's pulling good once again. Mileage is even better now so I'm really feeling better!
Hick-up explanation.
After work the day after I got her back, I took a 300 mile trip for the weekend up to Sebring for a Race weekend. Horrible rains and the truck started running really rough. No Power and shaking all over the place. Since I didn't have time to turn around I continued. Fuel mileage on the way up was 7 mpg! (No trailer)
Once in the dry, everything cleared up and fuel mileage returned to normal.
Not sure what caused it as there were no codes in the system but hope it never happens again! Getting too attached to this monster to let her go!
