Possible new customer for FICM ECM roll back
 

I am thinking about sending my FICM ECM in for a roll back flash. I have a 2004 Ford F-350 6.0 all stock. It has been into the Ford dealer, and they said they flashed the computer for me as a "favor." Now my best fuel mileage is 15.5 mpg on the hwy. I occasionally tow a 6,000lb camp trailer; the rest of the time is just daily driver. I would just like a little help with deciding which tune and roll back I should order??? I just want better mileage, and yet more power! When I pull the FICM ECM off, I will be adding a EGR Delete at the same time. Let me know what you think... Atlas 40? I would prefer to send my FICM ECM to them for reprogramming, but I haven't been able to get a hold of anybody yet. I left an email, but no answer yet. This seems like a company I would like to do business with... I just need to figure out how. Thanks for any help or advice. I am located in Southern Oregon.
