FICM Reprogramming & ECM Rollback lost MPG HELP!?
I took a trip with only the Edge CTS Programmer set on the performance canned tune and got 16 at 75 mph which i was pretty happy with. However I recently Rolledback my ECM/TCM along with the FICM and now can barely get 10 mpg on the highway!? I cleaned EBP Sensor and tube with no result so I replaced the sensor and again getting about 9-10 mpg on the highway at 70 mph. Anyone suggest anything else that may be wrong with the truck??
