After the inframe was done on this truck and rebuilt injectors, the DC PRO DRIVER DISPLAY on this truck start showing the MPG going down from 6.58, now is 5.99, but on practice (from pump to pump) is from 6.9 to 8.2 depends on the load. Do you know how to fix this? I tried to correct the revolution of the tires with DDDL 6.5 compering the speed on the odometer to the GPS, but the MPG on the display kept going down. Is it something that have to change with DDCT 4.5 ? Please help.....
