We'll i did it. I went today and had the ECM flashed with the tsb#18-003-06 Rev. A Also got the flash #08-026-06 Rev. A for the overhead display. As i was getting -40 degree readings here in calif. And the last one was #18-022-07
was for improved driveability and mileage as recomended by the Service Mgr. I filled up on the way home and i will report back as to my mileage in a couple days as to the results. One thing i did notice is prior to the flashes i did have a ticking sound just like valve ticking which sounded like a old 6. 9 ford i had. As of now the motor just purrs
like the day i bought it which was 7200 miles ago( 3 months).
