So i have an 03 with a 4.7 with my 2 inch lift i did new plugs fuel filter all new bushing tres alignment cleaned the tb and sensors and i was getting 24mpgs. At my last command i did upper and lower arms and trac bar. Motor and trans mounts rotors brakes and went up to 255/75/17 on moabs and i dropped down to 9 mpgs. I tried running bp premium and a cleaner and i still only get 9. Any ideas?
