Some thing interesting I found too that would be a Plus if it could be tuned around. There stage 4 package eliminates a major problem:
"Troyer Performance takes it to it's proper conclusion by additionally fixing several other issues in the standard calibration, the most important of which is the returnless fuel pump operation. We rewrite how the returnless fuel pump is controlled in several aspects that will now allow the factory PCM to accurately track the actual fuel pump flow rate and eliminate the problem of the fuel pump immediately hitting 100% duty cycle even at low rpm whenever full throttle is used, so we take care of that as well. These changes result in increased power-handling capacity of the fuel pump so that it can easily support even higher power levels at a significantly reduced duty cycle without the use of a BAP or other such device, as well as allowing the PCM to accurately track the actual fuel pump flow rate, complete accurate datalogging, and allows the system to consistently run at 39 PSI pressures at the fuel injectors as Ford designed under normal operating conditions (including full throttle), while still retaining the ability to deliver higher pressures if actually needed - thus retaining the normal safety features of the Ford electronic returnless fuel system. This process also frees up additional power, as the PCM no longer has to deliver extra voltage "on the fly" to the fuel pump due to an inaccurate fuel pump voltage table, and thus it no longer "robs" the ignition system of power that, in some cases, reduces engine output by 8-15 RWHP."
