From the website:

"Unfortunately, this year also saw the release of Engine Control Module (ECM) and Fuel Injection Control Module (FICM) updates that limited power output of the engine and severely degraded fuel economy. Also, in an effort to reduce further issues on the '03 and '04 model years, the same power limiting calibrations were loaded into any vehicle that happened to wander into a Ford dealership for service. Often, these "updates" were applied without the knowledge (or approval) of the vehicle owners. Imagine the surprise of 6.0L owners everywhere who went in for a simple oil change and lost 3-5 MPG INSTANTLY!"

"Often, customers with later ECM strategies will not see the same results from a FICM Reflash that customers with earlier ECM strategies do. Ford dealerships do not have the capability to reprogram your ECM/TCM to an earlier, more desireable calibration; PHP, however, can! If your current calibration is VXCF7xx, VXCF9xx, VXAP2xx, or VXBC9xx, we strongly recommend that you request an ECM/TCM rollback in conjunction with your FICM reprogramming."

thats what I was afraid of that the dealer would not re flash to previous code. I have been told that even with the new VXC9 code on my ECM and now new FICM, that if I run custom tunes from people like MATT at GEARHEAD they can tweak their tunes so that they can regain the power loss and with that hopefully a few of the MPG depending on my right foot. I ran MATTs tunes before I got the new FICM and talked to him since. Does this hold any weight or is going threw PHP my only real option to get back what the DEALERs have stolen lol?
