The custom PHP FICM programming takes all of the best things from all of the various FORD OEM programming strategies, rolls them together, and then adds in its own secret sauce to provide better drivability and the possibility of better fuel economy. On an 05 Excursion that had the latest version of Ford's software loaded on the FICM, we noted gains of about 2.5mpg in mixed highway/driving and much decreased turbo spool-up times with the 'Atlas 40' tune on top of the SCT 'street tune' that was already loaded. With the tune in place, when the light turns green, you go and go almost immediately now. The truck drives more like a gas truck than a diesel. Crazy spool-up times are a thing of the past!
