I have a 2003 6.0 and a while back I had Bill roll back the FICM to the earlier strategy and the ECM to a custom rollback program. My question is I see the FICM programmer for sale and the Atlas 40 and Atlas 80 programs and wondered what is the difference from my rolled back 2003 stragegy to the Atlas programs?

The rollback just changes the FICM strategyd. The FICM tunes give more power like a SCT would but instead your tuning the FICM. FICM tunes and PCM/ECM tunes combined work great.

You should see a additional power gain with the A40 or A80, the magnitude depends on how much power the ECM programs Bill made for you make. I don't think you'll see a mpg gain though, as you have the "mileage FICM program" already.
